Question about 2001 Toyota Corolla
A compression check revealed zero compression in two cylinders and 50 psi in the other two. No coolant loss. No contaminated oil. A leakdown test showed loss through inlet valves. A "wet" test saw the compressions shoot up. The engine now starts and shows 170psi compression with the engine warm on all cylinders. Is this engine prone to sticking valves? If so, do additives work as a long term cure or am I going to have to strip down?
How about some history.. like was it running OK and then was parked, and later would not start? or has it been sitting? or quit while driving down the road?? Mileage? Does it run good now? If so I would recommend using Chevron Techron Fuel additive to clean up the injectors and back of the intake valves. That could help if indeed the valves are a problem. Some repair shops have a Motorvac or BG Injector cleaning/ intake manifold cleaning that would possibly help that.
