Hi Guys
My 53 Meteor recently rebuilt (Apprx 500 miles since) has started burning oil..... Blue smoke etc
I've stripped it down and the left hand cylinder is the worst of the two. Piston crown badly coked up with oily black deposit.
Engine is on +0.30 bore.
Top Compression ring gap = .037" Second is .040" and oil ring = .046" .. The max wear limit is .625" ( 1/16") so plenty of wear yet to go. (Left cylinder measured as its the worst of the two).
When I rebuilt the bores were still showing the honing marks so all good and measured up nice and parallel etc.
The pistons both looked fine (6.5:1) so were re used I fitted new European rings from Messrs. H and gapped them to .011"- .015"
New valves and valve guides with valve stem seals were also fitted...
I'm currently a bit miffed....... The ring wear seems allot for basically 3 or 4 rides out!
I've ordered a pair of new "Higher Compression pistons from our hosts (8.5:1) and gaskets etc.
Anything else worth checking before I proceed further?
