Prob not in right section sorry. need thoughts please.

Bought a second hand 1660cc low comp bottom end , oversize pistons skimmed. Sat for 9 months. Paid £250.

Had it fitted, got car backlast night and smokes a little. Today it smokes a fookin lot. (more than i do ) Lost power today as I went past PJ Motosport. Thought i'd pop in and see paul for his thoughts (top guy)

Oil pissing out of plug 3 when took out. Paul did compression test and cyl 1 2 and 4 was 170 but cyl 3 was 140. Stuck a wicked camera inside and all valves dry which is good. Timing spot on. Paul is unsure until he looks properly tomorrow. What you guys think (stu??)

Or have i been fooked over by buying this botom end.

Thanks guys!

**Big thanks to Paul (pj motorsport) for looking so late in day for me**
