Turn the emgine over one full turn every time you bolt another item on. That way you will ensure nothing is too tight or causing problems

Ok, did allot of cleaning and blowing air through oil ways! the piston ring compressor did fit in the crank case , so although the pistons had to be fitted from the bottom , and the new liners were not chamfered, they went in quite easily.

1 clean and clean and clean. then clean again.
2 wipe all feeler gauges befor use.
3 Good torque wrench.
4 Lots off clean oil.
5 take your time.
6 soak paper gaskets in water before use.
7 get a white paint narker and mark all TDC marks
8 Get a blue paint Marker and mark all botls etc when torged up.
9 get an18" length off hard wood. This will lock the crank when tightening it. It also can be shaped to do the same for the cam.
10. Oh yes you will also need an understang partner

Wrinx, You must be a braver man than me. I didn't dare ask why after a lifetime in the Motor Trade and as a College Lecturer. It is a new idea to me too!

I can remember being advised to soak copper/asbestos gaskets in water and can only assume paper ones are soaked for a similar reason. Confused

What is that reason Pigtin??
I do know that cork gaskets shrunken by age can sometimes be redeemed by prolonged soaking, but I would have thought soaking paper gaskets would just make them more prone to damage when fitting. As for copper and (what used to be) asbestos gaskets: I have heard of soaking them, but I can see no point and I have never seen manufacturers instructions to do so anywhere.

Paper gasket soaking seems to me to be in the same realm as throwing away an air filter because the engine will run 'better'.

Jim.

Jim,

I've used the soaking method to salvage older paper gaskets. I have a '38 Buick and '47 Jaguar that I had original gasket sets for and in both cases the paper gaskets had shrunk. Soaking rejuvenated them and made them pliable again. I can't see the point on copper/asbestos tho'.

Seem to recall being told, in the case of copper/asbestos, that soaking them made them swell; and when compressed they would assume the shape of any imperfections more easily. This may well be so with a sv engine where head distortion may be more common. Still the logic seems a little dubious and it may be a myth... must be someone out there knows for sure?. Confused

Hi Dave, a little drop of oil on EVERY nut or bolt will help to keep the torque levels more consistent and always trust your feelings. If you do not think something is right walk away and have a cup of tea. A good mechanic knows when to get the hammer out.

Pigtin, It may be so that asbestos swells in water, but what happens when it (presumably) dries out and shrinks? In any case, unless it is an old-stock gasket it is not likely to be asbestos. The substitiute may not behave the same way.

Much better, I think, to make sure the imperfections are removed permanently and properly than rely on soaking. As far as paper gaskets are concerned, they generally are so easy to make using a small ball pein hammer it is not worth chancing the soaked gasket.

Jim.

.

Soak the paper gaskets in water.



Why?

Simple, it allows them to sit with ease on the surface of the gasket face, allows them to flex and they swell a little.

After all, as Tesco say.

Every little helps
