I got a car six months ago and it needed some work done. I used assembly lube on my lifters before I re-installed them. I used assy lube on everywhere metals touch so I thought the lifters would fall into that category. I didn't bleed them first. I started the car for about a minute and everything seemed fine. Now I've read a person should not use assembly lube on lifters as it is too thick and that I should do a compression check. What are your thoughts? Harm or no harm?

Thanks for reading.

I have used assembly lube on flat tappet lifters and hydraulic lifters. I have yet to have any problems in the engines I've built. As long as you did not fill them with assembly lube you will be fine. I am assuming they were used lifter that had been running in the motor before correct? If so they will still have a little engine oil in them. You should have bleed them and filled them with 5w-30 and used assembly lube to instill them in to the head.

No harm no foul. You're fine.
