cylinder compression ratings
 
Hi new to site. Just recently was given a 2001 se sedan from a friend at work. Car has 200,000 kil.( 120,000 mi.) on it.Motor is the 2.0l SOHC which has sucummed to the famous valve problem.We have already pulled the engine out and have already found to low mileage engines from a nearby auto wrecker. I'm want to know what the normal cylinder compression ratings are for this engine and what are your opions are about putting this car back on the road. The car is in excellent shape inside and out has most options for the year. If i purchase one of this engines by the time we get it in and get the car back on the road i will be into it for around 1800 dollars.I'm giving the car to my daughter and with the history of these engines i just was wondering what everyone thought.( P.S. live in bc canada and even at 2000 dollars the car is at the low end of listed used prices here in British Columbia.) Any comments appreciated

Cheers Colin

Do not put a junk yard motor in the car.Buy a head with the valve seats replaced.Do a search on here you will find many points of view.

Thanks for the advice. The person who gave me the car drove it for almost 2 hours at highway speed after valve seats dropped so head and motor are toast. The motor i'm looking at is coming out of a 2002 write off. It has a 126000 kms on it and the cylinder commpressions on all four are between 181 and 188. Should i look at taking the head off it and get the vlaves redone before i run the engine. I also was unsure if these were good compression readings. Any advice is welcomed.

Your compression is good.These engine are known for dropping intake seats.If it were my car I would do the head work before the engine gets swapped out.

compression sounds great! if you swap the head out, with updated one, you will have a good motor.

here is a link that explains the updated head.

Hi Kyle,

If i take head off replacement motor and have local head rebuilding shop redo valve seats would that be worth the money.

wiredFocus 06-11-2012 12:31 PM

I think it would. But call around to make sure to the different shops to make sure they know about the problem. I would not take it to a shop that has not heard of this particular problem. Find a shop that knows about it and has done a few. If not, I would recommend the ones from the link above. keep us posted

the motor i talked about earliar in this thread fell through but i have a line on another one with 140000km and compression ratings in all four cylinders of 155-165. these ratings are lower than the ones mentioned above but are they still good ratings.

thanks colin

Yes, not a problem until 120 or lower............as with many engines.
