low oil pressure or the seal on the roller tappet is old and it takes the roller tappet a minute to pressurize again.
YES it does and it is a roller cam and hydraulic lifters.
Probably not, unless they were added later. It should have roller lifters however.
No it does not. Chevy did not start using a roller cam until late 1995.
yes like 350 engine
They all had hydraulic lifters. To determine if it has roller lifters, you'd probably need to take off the intake manifold and have a look.
No, first generation 3.1 does not, second generation does.
It takes about 6 hours and be sure to soak the new lifters in oil over night.
No it is not. It is a factory TBI / Throttle body injection, None roller camshaft 5.7L 350 engine.
The 1990 will take flat hydraulic.
If you have a 2001 or newer engine, it comes with roller lifters and roller rockers from the factory.
when did Chevy vortec come out
Take off valve covers, heads an intake manifold with throttle body, pull out lifters and pushrods and simply replace It's not necessary to remove the heads for this procedure.
Doesn't matter on a roller lifter. Flat tappets must remain with the cam lobe they were broken in on.
vortec is a brand name Chevy started using on 4.3l motors in 1986.
No, the 1992 Chevy 350 (5.7L) V8 is not a Vortec engine.
There are no provisions for valve adjustments on this engine. Tighten rocker arm nuts to 20 ft lbs torque and you're done.
how do you ajust the lifters on a Chevy s 10. its making a taping noise
Yes it does. Chevy did not use solid lifters in that engine.
The 4.3L would have 12 hydraulic lifters.
If we are talking about valve lifters, remove cylinder head and pushrods and lifters will be excessable.
99.9 % of all Chevy small blocks and big blocks came factory with HYDRAULIC flat tappet lifters. Starting in late 1995 Chevy went to a HYDRAULIC roller lifter. Actually, the small blocks started coming through with roller cams with the introduction of the raised-rail heads around 86 or 87. Pretty sure the big blocks went roller when they switched to the non-adjustable valvetrain around late 80's, early 90's.
It is most likely a normal condition. The engine needs to build up oil pressure to lubricate the rollers. No damage should result. it is not the roller lifters it is the piston pin it has a slight amount of play and when the piston heats up the aluminum will expand and quite up
V-8 engines have 16 lifters and the V-6 engines have 12 lifters.
