Timing/oil pump chain


Recommended Posts

Dom,I am confused.At the beginning of this post the engine was out of the subframe and there was a tooth missing from a gear.Now you are taking off the valve cover and chain cover with the engine in the car.Are you working on two different cars/engines?CANMAN

Yeap! The previous picture are from a "for parts" engine I got. I open this one to see how the chain case are made and I found the missing tooht sprocket! I tought that the engine on my car had the same problem but... no! Now, I'll try to sell it as soon as I can but if I can't, I'll drive it as far as the engine blow. Both chain are ok, camshaft are great, the lifters dont leak, the cranksahft and rod dont have any endplay... so, what can I do now?? I'll drive it even if the chain noise are there. It's maybe normal. I have replace the alternator too. I tought that was the noise source but... not much! I'm tired to dont find. I think to myself "f*ck off". Enought is enought! Dont want to wasting more $$$ and time! I waste all my sunny weekend to work an this car!! I'm not realy happy. :angry: Have a great day!Dom :)

If your car is going to be noisey then I would make a good noise. I would put a tag axle and a Detroit in there... just think of all the smiles you would get from the old truckers when they hear you coming!Sorry you wasted your weekend but I bet you will figure out what the problem is. Good luck!

Salut mon ami kiki. Je vois que tu as encore des problème avec ta Smart. Ca ne te lache pas. Bon courage.

Hey Joce! Ça va? Haha! T'as tout vu juste! À l'infini les emmerdements avec la "smarde"!!! J'en viendrai jamais à bout je crois!! C'est près de 30000$ de réparation qui ont été mis sur cette voiture depuis que je l'ai acheté neuve en 2007. C'est complètement démoralisant! Anyway... Anyhow... I hope the électric smart will be more reliable!

Canman: The engine with the "thoots free" spocket is too worn to be just repair with my new sprocket and chain kit. The oil pump stoped to roatate due to missing thoots and the engine ran without oil pressure for too much time. Unfortunatly, the crankshaft are scrap and camshaft suport bushing too. :( But for the moment the engine on my smart (even noisy) run great. Of course, this morning I must replace a wheel bearing and take a look why the rear brakes stay apply but... it's become normal for me. It's a smart!! ;)MikeT: Yeap!! I went to more than 27000$ wasted in this car (including repairs under warranty). C'est "VRAIMENT" un citron!!! Probably a car built some monday morning or friday afternoon... I dont know. :/

Dieselkiki's engine was OK. He became VERY FRUSTRATED when he worked on the smart:

'' Nothing wrong on both chain!!! 5h on job for nothing!! I'm very angry to have waste my time for nothing!!

Both chain are ok! All sprocket are ok! All guides and tentionner are in good condition... where is the problem?? Hello??? No body can help??''

Sounds to me that he sold a running smart that he thought sounded funny.

I am having a similar noise problem. It appears to be coming from the right side of the engine, somewhat forward. I am attaching a short sound clip with the ticking noise.

Any comments would be much appreciated. The oil light is not going on by the way.

Are there any shops in Toronto that do this work cheaper than MB? I don't want to risk driving any significant distance.

I would recommend that you make the assumption the chain tensioner of either the cam drive or oil pump drive has failed and act accordingly - i.e. don't drive (glad you mentioned that) and have them replaced. Should cost about $1200 to have a dealer do it. No oil light yet is a VERY good sign!

Independent service options.

If anyone knows of more please add them.

The cam chain can be checked through the oil filler. Use a clean long screwdriver to check for slack on both sides, should be none. Don't put the screwdriver in with the engine on (doh!) but do use a length of hose to listen for the source. If it is a chain problem there would be a lot of noise coming from inside the oil filler hole. If it is an exhaust leak there won't be. The video does sound like it could be a simple external exhaust leak.
