1993 Corolla camshaft

Your expert opinion is invited:

Corolla 1993 7A-FE 1.8 L

Is there a way to determine the correct position of the exhaust (front) camshaft, independent of the gear markings? (i.e. the shaft itself).

I torqued the timing belt pulley counterclockwise with the camshaft gears stopped by a rag (don't ask) and damaged the timing set-up.

I think that I twisted the timing pulley counterclockwise on the exhaust camshaft, or possibly moved the camshaft gear on the shaft itself.

The car runs well, but makes a very subtle 'exhaust valve noise' - that is, a little like a motorboat (not quite as much as a Ford 302 with the valves burned wide open!).

I would like to verify all of the parts in correct timing. I know that there are 2 sets of marks on the camshaft gears: I want to check that these are set up right too. Do you know, is it possible to twist the gears out of line?

Are there markings on the shafts themselves?

Thanks for your comments - Jack

Thanks Ray O.

With the mild weather it won't be too hard to pop off the timing cover and look things over. You're right about the hex forms on the camshafts.

I appreciate the advice a lot.

You're welcome, I hope you can figure out what's going on.

good luck!

Unless you really reefed on the wrench, the gear train should be OK. You may have jumped a tooth. Check to see if the cam keyway still lines up with the slot in the pulley. Make sure the marks on the cam gears line up. Recheck timing as Ray O states.

Not related to this thread, but on a side point, I recently did my friends Renault Megane (Phase 2) - you probably have never seen one over there. Both the cams AND main timing pulley are keyless sprockets that lock in place by torqueing up the bolt. To do the job you have to lock the crank in position with crank locking pins through the block and lock both cams in place with a plate up top. The slightest bit of stretch you get on the belt while torqueing screws up the timing and need to slacken and re-do with a new stretch bolt on the crank. Even a main dealer buggered it up on another one I know. Might be easy to do in the factory but they quote nearly $1500 for parts and labour for a belt change on a $3000 used car!

Sounds like Renault hasn't improved much since I had a Dauphine back in the early 60's....LOL

One of my former co-workers worked for AMC during the AMC-Renault venture, and he said that 100% of his Renault company cars had a problem, and about half of the problems required leaving the car at a dealership overnight due to lack of parts or due to difficulty in diagnosis. He was not a technical guy, so he always had sleeping bags, bottled water, road flares, overboots, mittens, and a bunch of change for the phone booth.

Another former co-worker came from Peugeot as a field technical specialist, he was a great trouble-shooter.

I wont tempt fate but hers has only had outer CVs and a dodgy stat in

100K miles so thats not too bad. But my mates late model one has had 3 out of the 4 coil-on-plug coils fail which is a pain in the arse. Oh and the boot catch falls out with astounding ease. All in all though you get 47mpg from a 1.6 16v with 115 hp, so its not all bad. Ive not had a peugeot since my old 205 but that was so basic it was bomb-proof. I think as soon as the french manufacturers ventured into the technical side of modern cars it was a possible step too soon. Theres been so many software recalls on peugeot cars it amazes me and they seem to fall apart with ease these days. They're all in such a clammer to make the cheapest possible car in its class that they fail to realise people want them to work.

I do not have any recent experience with Renault or Peugeot so I am not in a position to say whether they make reliable or troublesome vehicles. Their past reputation in the U.S. was not stellar, so they would have to either offer a very long warranty like Hyundai has done here and/or offer a very attractive price.

'not stellar'?

ROFLMAO

I have no recent experience either, but if my '58 Renault Dauphine is any indication I would not say 'not stellar' would be an accurate description of my 'fun' with that POS...LOL

LOL they arent THAT bad guys. It seems nothing quite matches a Toyota for trouble-free motoring but id not put peugeot at the bottom of the list. Fiat maybe. Pug/Cit are just generally budget cars that do the job and have the odd niggle - theres a lot worse.
