After looking a bit deeper in to the engine noise, the solid roller lifters are coming out off the engine.

i watched the video......if those lifter rollers are flat spotted, then they were not rolling all of the time going over the lobes of the cam. i would suspect there are grooves worn into the cam and new lifters will only be a temporary fix until the cam wipes them out too....look closely at the cam....make sure the lobes don't have deep witness marks where the lifters ran on them. if it does......its new cam time....

Hi,

Finally the engine fitted with the new parts, i. e. roller Rockers, valve springs, push rods, mechanical bar roller lifters, new distr. gears, oil pressure sender and oil temperature sender changed. Heads/Manifold port matched and valvejob made. Melling oil pump checked and cleaned.

After some humpady rumpady noises, the engine starts running.
All disappointing noises from before are gone and I think the result is ok.

Water temperature is ok.
Oil temperature is ok.
Oil pressure marks "Zero psi" (new Sender from Summit sww-279a/80 psi).
I replaced the new Sender with the old one and it marks 40 psi idling 850 RPM.

Before replacing all the defect parts, oil pressure idling was 60-70 psi. Oil flow on valve and rockers went well and fluent.

Comparing now idling 40 psi at 850 RPM looks like a rivulet.

Questions:
a) How can I check the new oil pressure Sender?
b) How can I check how much oil has to run on the valve / rockerarm area be idling 40 psi?


Thanks, Rico
