driversdomainuk 8 Posted August 12, 2008 Hi I am stripped down my engine this weekend to try and get to the bottom of the low oil pressure issue with my Mi. I do have a spare 1.9 8v engine which has a new bottom end, oil pump, bearings etc...Is there anything which I could use off this 8v bottom end which would fit a 16v bottom end....? Thanks Share this post Link to post Share on other sites

Thanks Nope, the only thing that'll fit is the oil pump, sump and spacer plate. You dont want to ever reuse bearings and the 1.9 8v block has completely different oil/water ways and pistons rods crank etc. Share this post Link to post Share on other sites

How can that be? For a starters the 8v pistons are dished surely the compression ratio will b completely out? Just curious, if the 8v bottom end can be used then fair enough, but never heard of it without some major mods before. Share this post Link to post Share on other sites
welshpug 1,657 Posted August 12, 2008 never said the pistons were usable. Share this post Link to post Share on other sites
Miles 331 1 Cars Posted August 12, 2008 The blocks are fairly similiar really, Just the spray bar and some extra ribbing that differ's. Many 16v blocks are used on 8v builds. Parts wise everything is swapable bar the pistons and rods unless you get them machined, Bearing's I would not use again but it's your call really. Oil pumps rarly give problems unless it's a cheap pattern one Share this post Link to post Share on other sites
