- Q: How do i use a valve spring compressor. It looks like a c-clamp, so don't tell me how to use a smaller one, but the bigger one.Thanks
- save yourself the hassle and throw that thing away go back to your local auto parts store and buy the l shaped spring compresser should be about twenty dollars make sure vehicle is at tdc remove rocker arm bolt remove rocker arms going valve by valve do not mix them up must go in exactly the same order they came out now lightly tap the top of valve with a rubber mallet will help loosen retainers place compresser on rocker arm stud take r.a. nut and tighten till valve locks fall out or can be removed very small dont lose use compressed air to hold valves in place at tdc sorry that should have been first not hard but not easy to do rebuilt 350 motor from the guts out spent alot of money on spring compressers only to find out the simplest one worked the best the one like u got will give u hell i tried napas version craftsman all of them trust me use the L bar

- Q: I have a 1993 Oldsmobile Cutlass Supreme and I think I have the case of the blow-by. The engine had high mileage, but was rebuilt b/c it stalled while driving. 3.1L V6 gasoline engine. The fuel filter and the fuel pump are brand new. Now we have the same problem a few months later. It stalls while driving. Its been sitting a while and won't start by itself, so I pulled off the air intake hose off of the air filter to spray starting fluid into it. I noticed oil puddled in the air intake hose, so I looked for the PCV valve on the rocker cover. There is a tube going from the air-intake hose to the rocker cover. I popped out the tube from the rocker cover and there is no PCV valve. Just tube. Is that where the PCV valve is supposed to go? If not, where can I find it on the engine? And could that possibly fix the blow-by and the stalling engine? I'd appreciate any help. Thanks in advance.
