(ANOTHER) silly question - I've got 3 seemingly identical o-rings in my gasket kit. I'm guessing one replaces the o-ring on the oil pickup, and the other two on the bottom of the oil pump?

Edit: one more silly question while I'm sat here asking them - an associate down here at the workshop has advocated sticking the sump gasket down with a smear of RTV, rather than the carpet spray recommended elsewhere on this forum. Any thoughts? Also, by carpet spray, are we referring to this sort of thing?

You've answered your own question on O-rings. :)

Sticking cork gaskets down keeps them in place during assembly: the gasket does the sealing so the adhesive doesn't have to be permanent. A smear if grease will do if the gaskets align well.

Carpet glue = contact adhesive in a spray can.

Black silicone RTV can be used on the gasket and end seals junctions when fitting the sump.

Quick Q - I'm just knocking the old core plugs out of the head. I've done the bigger one at each end, and now it's time for the various tiddlers. It appears that there's 4 on the exhaust side, and two on the inlet side close together. Is that right?

It also appears that my ebay set doesn't match what I'm seeing. I've got 6 small plugs, but in 3 different sizes (two of each)...

Thoughts appreciated!

Matt

Earlier cylinder head has 8 core plugs.

Nominal diameters -

Front and rear (2): 1.1/2 inch

Intake side (2): 3/4 inch

Exhaust side (4): 5/8 inch

This engine is out of a 1974 van, does that count as early?

My set appears to have:
- 2 x 5/8
- 2 x 11/16
- 2 x 3/4

I guess I need to find two more 5/8" plugs then...

Later head with exhaust valve rotator caps introduced from Ch. Ch.FY600001- (start of 1976 production year) doesn't have the 4 core plugs on the exhaust side.
