Faq:
My 1995 240SX ran great for 3 years, through last night. This morning it cranks over fine
but won't start. It sounds like it doesn't have any compression. What's going on?
Solution:
1995 240SX, no engine mods. Worked great for about 60K miles, then one very cold morning
about 8 months ago it wouldn't start. It cranked over just fine, but sounded like it
didn't have any compression. Lo and behold, there was NO COMPRESSION. Blew compressed air
through the spark plug holes with a leakdown tester (which was reading an alarming 100%!)
and listened to the exhaust pipe and intake. Air was getting through the intake valves. I
figured the chain had broken and all valves had bent. As a last resort, I pulled the valve
cover and sprayed WD40 on the tops of the valves and let it soak a while. Suddenly I had
compression again, the car started and ran fine. Turns out garbage had built up on the
intake valves from a constant charge of especially substandard (Arco) gasoline, eventually
making all valves stick open. I haven't had the problem since, and have been using only
Chevron with Techroline. This gas has come recommended by many who know what they're
doing! Do your valves and injectors a favor and use it. No, I don't work for Chevron, but
just use some kind of clean gas and be mindful that it certainly makes a difference!
