Strange Motor Problem, Oil Consumption

[Excaliber]

I would not assume that ALL engines, particularly after market style engines, will benefit from synthetic oil. In fact, synthetic could be a problem for many of them.

I'm not convinced it's always the best choice for a new car either. Manufacturers have various reasons for using synthetic, sometimes in THEIR best interest, not yours, or the motors.

Thanks for all the replies, all good info.

I'm going to go about this one thing at a time.

I changed the oil back to no synthetic 20-50 Castrol and no change in the oil consumption or wispy smoke, oil smell.

Next on the list is to replace the intake gaskets. Considering that the two middle plugs on the passenger side are the only ones showing oil burning, it would seem the intake gasket may be leaking in that area and letting both cylinders suck oil at the same leaking spot. Seems reasonable to me, so I'm going there next.

If not that, then on to the valve stem seals, but really would be strange to have two of them right together go bad at exactly the same time.

Thanks again, lots of help on this board.

Wayne,

I would like to hear what the outcome was as I am having exactly the same type of issue. I'm thinking it is either a sloppy valve guide or valve seal.

Let us know what you found...

OK, ready for my next step in solving this oil consumption/smoking.

Intake gasket for the AFR 205 heads and Vic Jr. FI Mass-Flo manifold.

Can anyone help me with part numbers for SCE intake gaskets that will work with the injectors....or maybe they are not in the way.

Looking for experience here.

Thanks.
