1993 Q45 top end knocking ????

[jodnny31]

I wanted to see what you meant by HLA, would this cause the whole engine to lose power, i mean when i drove this car up on the car trailerIt barely had enouph power to make it up on the trailer..

It's a very loud knocking noise with loss of power on the top end passanger side.

I took the passanger side valve cover off, and to my surprize(not) it was black and crudy inside. which means this man lied to me to sell this car to me OR he never took care of this car at all...any idea's on what i have to do to remedy this engine knock, I don't think its a rod, but i could be wrong..

How do i clean HLA'S ..

I read the article that i recieved in my email, about the HLA, and how to use different oils and cleaners for the engines ot make it run better.

I guess i'm old school when it comes to working on cars, just lifters and push rods and rocker arms.

I appoligize for any inconvenice on your part, because i was only trying to understand the concept of the lash adjusters.( something new to me).

I think i have an understanding now, and i will try to clean these the best i can..thank you so much again,John
