Ok, my 2wd saff has been smoking on tickover, but seems to disappear after a 10-15 min run. Doesnt smoke much if at all after this. Start the car the next day, smoke again and so on. So i have removed the engine to change the sump gasket as it was leaking oil also.

I decided to whipp the head off and fit a complete upper gasket set including valve seals. I have so far found that the inlet from the throttle body elbow through to the trumpets etc are coated in oil. Now I would have thought turbo, but after removing the turbo, theres no sign of oil anywhere.

Could this still be valve seals and the oils just running down the inlet somehow ?? heres a picture of the inside of the plenum chamber.

 

I'd be looking at the guides for wear also m8!

 

Could well be rings/bore wear, even with good compression, oil control rings usually go first, mine was exactly as the piccie after 200,973 miles on original bores/pistons, but head was reconned, good compressions ace mpg and emissions 0.97 % CO, 137ppm on greys T34 with that mileage.

I have removed the head this afternoon. The bottom end looks pretty good. The bores show no signs of wear and no marks or scoring. The pistons do move a little movment in the bores, no knocking or slapping, just very slight movement which im assuming is normal. The pistons do have a couple of marks on them. At first i thought the were valve cut outs, but i think its where the valves have hit the pistons at some point.

Its a 200 block with 2wd head, so I imagine the bottom end has been bought from an engine thats had a snapped belt.

The pistons read Sp0.05 on one side and 90.775 on the other. Am I right in thinking that these are standard pistons and that it must still be on a standard bore???

Cylinder head has had a skim before, its reading 138.5 odd, nearly 138.6. Valves look straight and show no signs of being damaged, and all mating surfaces look good. I have measure the head surface with a flat metal rule and some feeler gauges, and all seem to be within Fords tollerances.

Im going to buy a full group A gasket kit including Head bolts and valve seals. Bolt it all back together and see how it goes.

I'm pretty sure the 90.775 is 1st oversize, the clips marks on the pistons are fairly normal, even with std cams etc they do have witness or kiss marks when revved high mine did.
Whilst it is in that state of apart ness it might pay to just take to a decent machine shop to get bores measured, the bore finish doesn't look very good at all can't see the cross hatch hone marks, these help to hold oil whilst running in to bed the rings in well.
