I'm Awesome
Hello everyone I have a 1988 Chevy c1500 that I’ve found a new problem with, it’s got a L05 5.7 liter 350 2 bolt main.
First of all I did a cam swap for a cl122494 cam from comp.
I’m not happy with the install as the cam was made primarily for Vortec heads and my engine runs lean now so it’s less powerful, I have no lifter tick and the valve train looks to be moving evenly.
I have Vortec heads in my possession but I’m not putting my nice new parts on my engine until I get this figured out.
The most notable failures of my cam swap are as followed this was my first time ever taking an engine part so forgive my stupidity: I didn’t have the feel for setting valve lash yet so I set it way too tight turning my engine into a misfiring mess that I drove on the road for a week, during the break in my drunk friend did not notice a coolant leak so my engine over heated twice. I quickly shut it off however and fixed the leak.
I found a small amount of silver covered metal that is normal for a cam swap I’m heard (flat tappet)
When I changed the oil the 3rd time there was no metal of any kind so I thought everything was well, on my next oil change however, I found an alarming amount of tiny gold flakes I could pick up with two fingers, a bit of copper covered dust and paint like silver colored dust, I still have the oil filter but have yet to cut it open yet
I have only run zinc oil in this truck, valvoline vr1 full synthetic zinc oil.
I have no rod knock or lifter tick, I do however burn half a quart every thousand miles, my engine also runs a good bit hotter but I assumed that was from it running lean due to the tbi not understanding the new cam.
This is my only car, my daily driver and work truck, it’s got 171 thousand miles on it and I change the oil frequently, I also drive like a grandpa no high rpm pulls until I’ve got it rebuilt to my liking
I’m going to a shop to get the rod and main bearings looked at on Monday, I’m going to try and drive as little as I can until then
A friend of mine says I need to use a high power oil pump and slightly larger bearings?
Could this just be old almost 40 year old bearing wearing out and I just got unlucky?
Thank you! All my Chevy information is from the internet, mainly this website! Y’all have a good evening
