Sorry to bother you again, I just realized that you have send me some pictures between each remove and installment procedure but may be they have been time out because none of them seems to apply to my case, I saw some volvo a/c diagrams...etc, can you send them to me again, thank you and best regards,
I need to replace the 2002 Buick LeSabre Custom Valve cover gasket to fix a oil leaking problem, have already fixed the one in the front, (near the radiator) a few months ago, need some help on how to remove the valve cover in the back (near the firewall), have talked to Mr. GMWrench as you can see from our previous email above.
I can see that there are metal tubes along both the front side and rear side of this valve cover, connected in the middle with a up-side-down U-shape tube, which sort of block the valve cover. Looking at what the are connecting to, my guess is that this may be the fuel injector tube lines? without removing these tubes, it does not seem to me that I can remove the valve cover and I could not get to at least one or two of the bolts that hold the cover.Did not see anything in your instruction about these tubes, or may be I did not understand you?Another general question, I assume that if there is a big arrow in any of the diagrams, the arrow is toward the front of the car, correct? How about right or left - am I sitting in the driver seat facing front? or am I standing in front of the car, facing the back?Thank you and regards, Paul
Hello i going to send a picture let me know if this is what your describing.
Those are the fuel injectors with the fuel rail attached.To remove that assembly you will need to take out the four retaining bolts.Then gently pull up or slightly pry on the fuel rail with a little pressure.Most importantly watch each injector as removed so the injector O-rings do not get lost it has happened to me before.Before removal of the fuel rails bleed off the fuel pressure so that fuel doesn't spray everywhere when released.Let me know if you need anything else.
The easiest way i found to bleed off the fuel pressure is to remove the cap off of the fuel pressure test port.Then use a small screwdriver and press slightly on the small schrader valve inside with rag covering the outside to keep from spraying until pressure is bled off.The fuel injectors should pull out with the fuel rails connected meaning that if you stick a screwdriver underneath the fuel rail close to the injector and give a firm pull but not to hard the injector should dislodge.You make have to start at one injector and move to the next one beside it and may possibly have to back to the first injector until loose.GM has a special tool for removal of the injectors but i have never used it and i will post a picture so if you want to look for the tool at your local parts store.The o-rings should stay in place but once and a while they will stay stuck in the injector hole.You should be able to buy those injector o-rings at the parts store but you can get them at your GM dealer.I usually reuse the o-rings after a quick visual inspection of them and what makes them go in easy a drop of clean motor smeared around the o-ring.
