HELP with a c4(lt1)
My best friends dad has a 96 c4 vette. He has been having to bleed the purge valve daily for a week now and water pump was barely leaking out the weephole as of tonight.Optispark was replaced about 2 years ago so I went ahead, Drained all of the coolant, took a shop vacuum and sucked out all the coolant and barely spilled any at all.(Did it last week with my ls1... dam water pumps) Opti is dry and clean, I need to clean the block badly.. Its a greasy bitch(160k DD) I am going to cover up the opti and do what i can with it... but I need some advice...
1. Any tips.. DO NOTs.. MUST DOs with a high mile BONE stock lt1?
2. I found some cracked vacuum lines and im fixing all kinds of little ****.. what all should I look for?
Hes been outta work recently and just got a great job and gave me his debit card so Im going to do it cheap, correctly, and fix everything that is needed.
Throw em out there
