360 LA squeel / scraping noise like drive belt on passenger side
Did you know?
that LA rocker shafts have to be correctly clocked
and that 318 rockers are different from 340s,
and among all of those are lefts and rights,
and when installing a high-lift cam, you gotta check the rocker to retainer clearance,
and the pushrod to p-rod tunnel clearance.
Oh and if you have aluminum valve covers, then under the oilcap is a tin baffle, that usually has to be clearanced to the rocker arms.
Thank you for the reply.
Yes I did know the rocker shafts have to be correctly clocked. Drivers side notch to the bottom towards front , passenger notch to rear bottom, oil holes at bottom, rocker arms also have a left and right which I have correct.
I dropped my heads and cam specs off at the local engine shop ( very well know builds high performance engines) to check clearances for the cam and if anything needed to be done for the valve springs that went with the cam.
I am unsure what push rod to P-rod tunnel clearance is I will have to look that up. Now the valve cover thing could be the noise, I did not check this, we do have alum covers, and it does should like an issue within the valve cover area.
Thank you for the reply, I will check that
Something to add, do not know if this would matter, but when we remove the mufflers and run open headers we do not have the oil pressure issue, oil pressure goes up 10-15 psi on start up and when warmed up during idle. No idea how that makes sense, but it does it.
Also, we still have the smog ports open on the side that the noise is coming from, could this somehow be making this noise, I know the tick tick exhaust leak are the ports, but could they also be making the odd noise as well??
Just some more info. Thx
