Toyota Camry



July, 9, 2007 AT 6:54 PM

We have an 89 Camry wagon with 156000 miles on it, automatic, V6 2.5 liter engine, no history of engine problems. Did a top overhaul after the engine lost power on an uphill due to a cylinder not firing; seems to have been a long-term problem that was not noticeable (except for oil consumption) until the failure. Now that all the valves and both heads have been replaced, and every single part in the engine is exactly according to the book (haynes and chilton) we are not getting any compression at all. Timing belt has been checked; everything is exactly as it should be. The only reasons we've been given so far are timing issues, but we can't find any. Any other ideas?

You are getting " no compression" when you test the engine with a compression tester? If that's the case, it could be a valve that's open, or the piston rings may allow the air out, thus no compression.

Who rebuild the engine? Could be valve problems or rings installed upside down. Recheck the T/Belt.

Do a cylinder leakage test to confirm the area of leakage.

The compression tests yielded no compression, but all the valves are opening and closing as they should be. After testing everything we've heard that the parts have to go back in one specific way, and just following the manual isn't going to put them in that one specific way, so we're going to rebuild again this weekend and see if it works.
