Noise from lifters after rebuild buick 455

I have a 70 455 sf engine that i have rebuilt myself. 0,030 oversize cast pistons, ta288-94h camshaft, all New bearings, New timing cover.I have problem With noise from lifters (i think it is the lifters). The oil pressure is very good. I posted a tread about this earlier: http://www.v8buick.com/showthread.php?254926-Collapsed-lifters&highlight= I started the engine Cold Without the valve covers and it took 2 minutes idling before the oil came out of the pushrod holes. Is that normal ? Please help me, what could be wrong ? The engine have cam bearings from TA, grooved type. All New valve Train, adjustable pushrods 3/4 turn preload.

check your rocker arms, i'm assuming they are stock units. see if you can tell if it is coming from one side or the other. if it is louder on one side then swap around the rocker assemblies. if the noise changes sides then you know what it is. good luck, i went through this last year, have roller rockers now.

 

Thanks Paul C, Can i use Stock cromed steel stage1 valvecovers With roller rockers ?

 

You can use stock rockers if you get the double thick valve cover gaskets from Finishline.

 

Hey Eivind,

As Paul stated it might be the stock rocker assemblies. I have tried the same thing, put on rollers and everything good. Had forgot about it and just made a motor with the stock set on. Noise is back.

 

Noise is only a symptom of the issue at hand. that being no oil up top. You get oil flowing out those push rods the noise will go away. My money is on a problem with the lifter itself. I believe they are not pumping up.

 

Thanks for all reply. The rocker arms and shaft are brand New, i am suprised if they wil make noise. Would like roller rockers, but they are expensive. What about the fact that it takes two minutes of idling to get the oil trough the pushrods an up to the rocker arms ? When the car is idling With the valve covers of i got no oil on the inner fenders, the oil is coming slowly out of the rocker arms. A friend of mine told me that his Chevy engine would spill oil all over the engine compartment if the valve covers are off. Do i have to little oil to the pushrods and pushrods/rockers ? The engine sounds Nice, and have the choppy idle like this camshaft should have. Can i try With another type of engine oil ? I tried to lubricate the rocker arms With oil from a can, but no difference in the engine noise. What would be the next for me to try now ? Can it be a front cam bearing issue ? Please help, thanks.

 

50 psi is high at idle, does it go down when it gets warmed up?
i had 50psi at idle and it would blow the filter seal at 3500rmp twice.

it had 30 psi with a drill motor turning really slow.
problem was in the oil pump.

 

Thanks. The oil pressure will drop when the engine get warm. I chanched the oil to 20w50 pennzoil, still valve train noise on both sides. Maybe the new camshaft failed during the startup procedure ? I have not lifted the intake off and inspected the camshaft and lifters, maybe this would be the next to do ? I wil be greatful for any advice, thanks.

 

Get that 20w/50 oil outta there, waaaaaaaaaaaaaaay to heavy an oil. 10w/30 is fine.

 

What method did you use to set the pre-load on the lifters? Was the intake off when you set the pre-load? What valve springs are you using?

The front cam bearing should be set in approx .125 to complete the oil circuit to the drivers side of engine. If that is installed wrong the lifters will be noisey on the drivers side only. What brand of lifters are you using? The passenger side lifters are fed from the same oil circuit that the mains are so if you have a oil problem there your mains will also. Are the push rods 5/16's adjustables? Have you checked for witness marks on the push rods where the might be rubbing where they pass through the heads?

 

Thanks for reply. The pushrods are 5/16 adustable TA1428. The camshaft and lifters are from TA (TA288-94H) I have set the preload 3 times, the first time With the intake off. The second time 1 turn and the Third time 0,5 to 0,75 turn. I have the dual super springs from TA and the correct retainers for the springs. Rocker arms and shaft are New "Stock type" steel. The front cam bearing are TA With grooved back side. I installed the front cam bearing correct, like TA said (lifter/valve Train noise are on both sides) I have not checked the pushrods for marks. The oil pressure is good, 50 psi Cold engine at 1000rpm. First startup after rebuilding engine it took many minutes befor i got oil to the rockers, i had to lubricat them by hand until the oil came out of the pushrod holes. Maybe the oil are leaking out from the lifter to pushrod ? The pushrods are turning around while the engine is running, so thats ok. Thanks for taking Your time. Best Eivind

 

The engine sounds lika a sewing machine

 

When you installed the "New Timing Cover" did you re-use the oil pump? Did you replace it with a new unit? If you reused the old oil pump, that may be your issue. This would lead to the lack of oil at the lifters which would transition into lack of oil through the push rods and the following rockers...

If you have another set of oil pump gears and/or housing, I'd swap them and see if you can replicate the noisy running condition.

If you decide to tear the intake off I would at that point put in some Comp Cams Pro Magnum lifters. They have a checkball in them and they will not bleed down and you will get more rpm (200-500) out of the motor with these. They hardly need any preload to operate. They have a real nice solid retainer on top to help give that light preload. They almost act like solids and will help out cams that have a fast ramp. This has been in my motor for 10 years now and I am using the Pop Mechanics cam but it is in a 350. 230-245 116 507-502 lift

 

Thanks Mark. I have New oil pump gears from TA correct installed With correct clearance (i used the gasket set from TA With diffrent gasket thickness) I Guess the oil pump cover clearance is correct when i have 50psi oil pressure at 1000rpm Cold engine ?

Thanks ! I may do that .

 

Hey torsdalen

How many miles did you run with this engine? Mine was also a bit loud after rebuild, but after 1000 Miles its very quit.... 230/240 118 LSA
I have the same detected with the long oil time, i primered the pump and it comes no oil out of the pushrods. After 1-2 Min Idleing the oil was coming...

be cool

Rob

 

Thanks Rob. I have barely used the car. Just a few miles. Thanks for advice, i will drive the car for a while before i considder lifting the intake off. What engine oil do you use Rob ? I switched from 15w40 to 20w50

 

I too agree, way to heavy for a fresh tight motor. Ive spun a rod bearing before on 20-50, back when i was young and dumb. ou:

 

Thanks Thomas
