Damaged cillinder wall what options
Turbo Mini Forums

Hi all

I now have the mini on the road ( we did a 7 eavening weekend two man wrecks to riches rebuild) and now in use I have worked out the current standard 998 engine is from 1974 low compression and a bit of an oil burner even after a cillinder head rebuild.

I had a good high compression 10:1 A+ engine sitting under the bench for a while but when removing the cillinder head for the above engine found two large chips in nr 3 cillender wall B*ll*cks.... I was planing to turbo this engine but i think it is now scrap eny solutions new liner ???? can we confirm it has moved on to the A series engine heaven?

It looks like a wrist pin has poked byond the piston at some stage as the scors ar oposit each other and in line with the wrist pin in the piston the scoors are about the size of a 1 penny coin??

Cheers

Andrew

You can bore the 998 upto +120 thou, and pistons are available, so depends how deep the scores are, you could try measuring them.

If it's beyond this then it's scrap. But 998 blocks are still cheap in the UK at least £40 usually gets you a decent one.

I seem to remember that if you use a block that was on an autobox you will need to modify the oilpump and feeds to suit a manual.Maybe this applies only to 1275,s ?.

Aha, Thanks for that bit of info, I will have alook at this, I can have the block cheap eny way mabe som useable parts in/on it.

Cheers, Andrew
