In need of some help please.

1988 S1. - 2.8 v6 MFI

Have the bottom end gasket set as photo. Please can someone tell me where the following gaskets / seals go as I can’t work it out and I can’t find my Haynes manual so struggling with this.

1. Thick rubber gasket with paper each face.
2. Little rubber blocks (assume these sit between the sump half moon rubber and cork)
3. Small seal, doesn’t seem to fit anywhere, crank Front and rear identified.

Looking at the set from Burton (second photo), this set doesn’t include the 3rd seal, item 3. So maybe not required.

Thanks in advance.

1. is possibly oil pump to block or oil pick up to pump ? Second thoughts that's more likely to be the little grey ones. Thick rubber, a coolant/heater pipe somewhere?

2. Rear main bearing cap sealing wedges.

3. Not required

It is not uncommon to have spare bits, gasket sets are often made to suit various permutations and applications of an engine.

Your a star. Would never have worked out where the wedges went. And definitely the looks like the oil pick up for the thick rubber gasket.

Have an issue with the coolant dowel to timing cover rubber rings, have modified them, but concerned what I’ve done may not be work. Will have to upload some pics when I take it back apart. Basically the rubber rings sit snug on the dowel, but the outside diameter is bigger than the hole in the gasket and the back plate, so would have to sit on top of them, which would prevent the timing cover from tightening up against the plate (with gasket between).

The diameter of the recess in the cover isn’t big enough to accommodate the rubber either. I’m of the opinion that the two black rubber rings are suitable for my engine, they look smaller diameter on the Burton kit.

Help please. In my gasket set are two rubber seals that sit onto the coolant dowels behind the timing cover, rhe dowels feed the coolant from engine to pump. If this isn’t perfectly sealed then looks like coolant will go straight into the engine oil.

My issue is that the two rings were bigger in diameter that the circle in the metal plate and the gasket itself, so rightly or wrongly reduced the dismayed so that they sit against the metal. When installed they just proud of the plate, so with the gasket on the timing cover guess there will be hardly any compression on the timing cover plate side at all, and this not forming a seal.

There is a recess in the timing plate, but not sure why, and this is much smaller that the seal itself.

Have I got the wrong seals??

Picture 1&2 are engine side, 3,4,5 are timing cover
