With hydraulic lifters what keeps valves from closing, what is the likely cause and what is the remedy?

Question:
VW factory reman engine, done 12000 miles. had one lifter collapse, fixed,then had to readjust lifters to factory spec. 2 turns from initial contact, but they are not letting the valves seat completely. would thinner oil help? using 20W/50 right now.

Answers:

my civic has a rattling in the front end that occurs when im moving?

That is thick oil, not sure why you run that viscosity, maybe someone suggested it to you. What is called for in the book?

I have a 2007 Honda CRV with a Service Engine Soon light on after 4K miles anyone know why?


Two turns seems excessive, but it sounds like you know what it's supposed to be. I think Chevy's are 3/4 turn.

Which, Truck, CHEVY OR FORD ? Why ?


Good luck.

How can I remove reside left on my window from removing tint film? HELP PLEASE.?

Are you tightening two turns? Sounds to me like you need to loosen two turns. The lifter will fill with oil to close the gap.

I want to buy DC Sports brute force long tube headers?

sounds like me first of all you need 5w 20 or 10w 30 not that thick stuff no wonder why the engine burned up poor thing. and if valves are seating then you got bent valves or warped head man damn

where can I look up all the available engines and prices for my car?

make sure the engine(crank,cam,valve is in the closed position when adj),if not you are over tightening not letting the valve close.Consult a manual for corract tightening procedure
