HI i am currently restoring my 3500s, the engine compression ration is 10.5.1 it was last on the road in 1986 the speedo shows 26k which i assume is 126k as i have no service history for the car, only the log book and the tax disc that was in the window.
I have started to inspect the condition of the engine which i can turn freely but have a couple of questions:
Would this suggest it was re-built at some point?
1. The end shells are in very good condition and marked 010
2. The piston linings are very smooth with no signs of scoring, but a couple are showing a few blackish discoloration marks as if there were spots of surface rust, some of the marks are the size of a 20p, the marks feel smooth and there is no pitting?
3. The pistons and cylinder head has a very thin and even deposit of soot.
However:
4. The oil is very black and sludgy, almost like tar and feels gritty but not metallic looking.
5. The rockers are coated in a thick coat of dried on black tar?
6. The Con Rods are covered in a thick layer of surface rust, but there is no sign of water in the oil?
7. The cam shaft wear looks a little uneven.
8. The hydrolic tappets are lightly dished on top but not all have worn evenly?
What is the general feeling: based on the fact it has probably done 126 thousand miles and sat with everything in the same position for 30 years?
Thank you for reading.
