Oil Engine rebuild

[chrispitman]

Just about to start the engine after replacing the cam and topend. Have some Silkolean Pro s 10/50 should I run the cam in then do another oil change or leave to the stardard 6K or yearly.

Use the silkolene, you only need to use cr@p oil post rebuild when you've changed pistons/ rings and shells, top-end won't be effected, if anything good oil will help protect the cam more during the initial run-in

Well come on what cam is it?

V8D Stealth Cam

I am sorry to go against the grain of what others have said but you should really be running the cam in on a mineral oil, the tappet to the cam lobe needs to bed in, in the same manner as a ring against a cylinder bore so to speak, kent cams/compcams/cranecams/realsteel/iskycams will not warrant any of there cams unless it is run in with mineral oil.

Well i may be fussy.....but i would run the the cam in on a cheaper oil anyways,and change it after a couple of hundred miles(filter too) even just to get rid of small fragments of gasket(and i dont care how clean you try to keep it theres always slight remains) and any slight material shed from the cam run/in process(and wouldent waste fuly syn for this)i would put fully syn/semi syn in after,this is just my cents worth and thoughts on the matter,and V8 racing i can see where your coming fromi think that being the case diesel motor oil would be ideal for this process.

When I did my cam, (well Rob did it really) I just ran it on Unipart 15/50 mineral for about 1500 miles. Then changed to a Semi synthetic (Morris oils)

10k miles on everything seems just fine

Diesel oil isnt that far from the truth! i am a bit busy at the moment to explain so go and have a look here http://www.hotrod.com/techarticles/engine/flat_tap...

What other grade of oil would be suited as unipart don't do a 15/50 mineral oil, comma oils show a 15/50 mineral on there website but the factors can't get hold of it.

What other greade would be best to use.
