  1. Oh and you need a long socket for head bolts. And I do not remember precisely,but I think it was T55, not T60, but maybe I am wrong.
  2. By thermostat mod do you mean the restrictor in bypass line?
  3. Hi Willy! I'm glad you are also freshening up the engine. I also started with valve cover and after finding this and that I ended up with bare block. In the meantime I also rebuilt the CP1 high pressure pump as it was leaking more and more. The seals were gone. The pump rebuild is fairly simple,only thing to watch is absolute cleanliness. I also scraped of the rust from the pump parts when disassembled, passed the pump heads and non return valve seats with 3000 grit sandpaper on straight block and with polish afterwards. I did use a lot of brake cleaner. And that did solve the famous knocking sound during acceleration. For the oil chain change also the tensioner and spring, I found that the old tensioner flexes to some extent more than the new one and the spring also showed some signs of wear. If you need any help I'm here.
  4. Thank you all for the nice words! I do not have a lot of free time, I am always working on some projects so I do not spend time reading the forum a lot, however as I already wrote if someone needs any assistance with engine rebuild or something else feel free to contact me through PM or email. Sorry for some photos, I realised later that some of them are bit blurry, but at the time I took them my hands were dirty and I didn't want to mess up the phone too much with oil and grease. For the AC at the end I only changed the condenser and the AC afterwards is running like new. I did other things, handbrake cables,rear quarter window seals,... I am still having problem of water ingress on driver side ( LH ). On the right side I only closed the hole for the screw on mirror holder and the leak is gone. However on LH side I did the same but there is still water coming in rainy weather, I have to investigate further. I am also having problem with gearbox oil leak and excessive play of inner CV joint in gearbox, but I opened new topic for that, hoping to get some replies. I think I am going to drop the engine again and dismount and disassemble the gearbox so that I can determine the cause and change the bearings when it's already opened.
  5. I have to add that I did not notice any play in differential bearings when I hold both CV joints pressed vs inside and try to move them.I have marked the spots in red which I think may be the problem ( worn diff housing or retaining ring ). Also there are no noises from the gearbox, it is running very smooth and gear change is very good.
  6. Greetings to all! After having done the complete engine overhaul and some other thingies my wife's Smart has been running ok ( apart from two noises that I still have to find the cause ). However a couple of days ago when I went to change the oil and install a modified filter housing I noticed a red fluid on the differential housing. It was ATF fluid from gearbox. I then investigated the cause because when doing overhaul I also changed both output shaft seals as well as input shaft seal. When I tried to move the inner CV joint on LH side ( driver side in Europe ) i found that the joint has a lot of play inside the gearbox/differential up to a point that I can create an opening in the seal of about 1mm or maybe more. Another thing I have noticed is that when I did this there was quite a pressure built up inside the gearbox and it escaped out together with some oil when I moved the CV joint. The CV joint on RH side does not have that play. I tried to press the CV joint versus interior of differential and it seems to me that then there is less play. Did someone have this kind of problem and if yes how can it be resolved ? I was thinking that maybe inside the cv joint there should be a spring creating a tension versus the differential and that the spring could be cracked but I cannot find a picture of the inner joint disassembled. Maybe the retaining ring on the cv joint shaft is worn ?? But I cannot extract the cv joint out of the gearbox without using a pry bar. I will drain the oil and remove the axle to verify in the next couple of days, I just wanted to see if someone can point out the things that can be consumed/worn to look out for if anyone had a similar problem. I did come across one post on this forum ( in another topic ) where someone posted the same question but no one replied to that.
  7. The hoses and connectors showed no leaks,not even on the quick connectors below the car ( I do not know if the hoses are upgraded or not - I did not find what is different about upgraded hoses ). So I think after changing condenser AC will be ok ( condenser is "eaten" by road salt from the looks of it )
  8. The next day again no AC ... I was pissed off, I went there again, he recharged the AC again ( that's a total of 1.8 kg of R134a ) and gave me money back nad told me that I should dosmount the entire car and take it to some other AC tech for diagnosing... It was 38 degrees C outside so I waited for 8 PM ( a bit cooler then ) and then dismounted the front end in 15 minutes. I took my "special" UV lamp ( 2$ ebay ) and illuminated the condenser and it shined bright green on both sides. I also removed the air filter and checked the evaporator and there were no signs of leaking. I then eemounted the front end and then I realised that the "green" condenser is easily seen through opening in the front bumper. So now I am waiting for new condenser to arrive, I will install it and then go to recharge the system somewhere else. This I wrote only so you all can understand why I went to do the engine overhaul myself because most of the workshops here are at the same level of expertise..
  9. I also went to recharge the AC system. After arguing with the guy at the workshop about gas quantity ( 620g vs 450g he claimed ) he evacuated the system,vacuum tested and charged it. I went away and the next day again no AC. I went there again to see what is wrong and he wanted me to leave the car there for a couple of days for them to verify where the leak is. We went away for vacation one week so I left the Smart there. I went to pick up the car on Monday, started it and the AC worked,but very weak. It was a very hot day so I thought ok. The guy told me that they checked everywhere for leaks and could not find any. He showed me the special UV lamp, a probe for inserting in air grilles to detect R134a gas leaking from evaporator, and told me that he recharged the system again and the Ac worked for 2 days in front of the workshop.....
  10. I also went to see my friend and tried two other smart cdis and they alsp have the same sound, I guess the sound is normal, it's just weird to me...having no experience with Smart. I started to notice some weird sound from timong chain case. It is noticeable on idle and it sounds like a bad tensioner,like chain is slapping around occasionally. I installed the entire timing chain kit ( sprockets,guides,tensioner ) from FAI/LUCAS and I cannot see anything wrong looking down oil filler cap hole. I guess I will have to drop the engine again and change the tensioner. I have read that there were some similar experiences and that remounting old tensioner solved the problem.
  11. Oh and I could have taken better photos,but most of the photos were taken with my hands half dirty and I didn't hold the cell properly so some are a little bit out of focus.
  12. I am more than willing to assist anyone when doing similar work or with any other problem. Most of the tutorials I saw for engine removal say to drop the entire subframe. I found it easier to do removing only engine and gearbox using hydraulic jack and the car remains mobile ( you can push it around ).
  13. I also removed rear side windows and changed the seals as they were leaking in rain. Overall the car power has increased significantly,specially in low revs. The engine is silent, the only thing is that when going in low rpms there is a sound like the engine is "knocking", similar to petrol engines with bad petrol or ignition adjusted early ( autocombustion,detonation ). I do not know if this is normal in these engines.After passing 2000rpm that sound vanishes and the engine is running very silent.
  14. I took the injectors to pressure testing and one of them had excessive overflow so I had them replace that element. Other two injectors were ok. This alone was around 130€. I installed the injectors ( did not find the correct tightening torque so I also tightened them by feel ),assembled rear hatch,exhaust,cross-member,poured in new oil ( Mobil 1 5W-50 ),poured new oil in gearbox ( Mobil ATF 220 ).I was surprised that in engine goes more than 3 litres of oil ( I think it was 3,6 lt ). I thought it was less than 3lt. I poured water inside cooling system for initial testing. If everything goes ok I will flush the system and fill with antifreeze. Oh, the three wires that go from engine harness to floor tray and then somewhere versus front of the car I didn't want to remove the undertrays, so I cut them in front of the engine when dismounting and now I installed 3-way waterproof connector so for the next time it's easier. I connected the battery, turned to ignition a couple of times to fill the rail with fuel and then tried to start. In a few seconds the engine was running at idle,smoothly, no smoke,no knocking,very nice.
  15. I transported the engine back to my father's garage and after assemblying engine and gearbox, installing new rear mounts ( front mount was already replaced and in excellent condition ) and other thingies this was the result.
