Can u still get Big end bearings?

Postby iety2004 » 01 Jun 2005, 22:14

Hi guys, last week my Kadett engine devloped a defect from a big end bearing on No4 cylinder when i entered a corner at a too high velocity.

This was due to incorect amount of Engine lubricant being useat thew time by the engine, this caused a loud knocking noise to be created when the engines rotating speed is decreasing and not being able to go over 60 MPH. (I.E Through in to a corner too fast with no oil in the sump! Engine FUBAR!)

I was playing with the idea of removing the engine and fitted a early Nova/Astra engine as these also used the 12S engine, but trying to source one of these is too much hassle so i think, even tho it'll be more expensive, to develope the Kadett even further buy having the Engine reworked, Lightened, balanced and the crank reground with new shells, I would remoe the head and rework it myself,

Get my Weber 40 rebuilt and then fit my Kent Cam and Weber on a ported and polished head, with lighted internals and higher compresion ration with home made exhaust manifold. This i hope would get me 85 ish bhp.

But can u get new oversized shells, and engine gasket sets

Cheers

Were these 1.2s not the same engine as was fitted to mk1 and 2 astras, and mk1 novas? I can't imagine GM radically changing the crank journal design between these cars, so I would assume that big end bearings will still be available if you are willing to look hard enough.

Well yeah, the engine number is the same, so there are the same engine, but i would rather try to fix my engine rather than just swapping for another one, think the job will cos 120ish most prob,

But at the moment i don't have the money so it might be easier to swap engnes, just got to try and find one

big end bearings and gasket sets are readily available mate just don't buy the first ones you see on ebay. let me know what you want and i will price the bits up for you.
replacement shells after a crank regrind are known as undersize because the journals will be smaller than standard. conversely piston sizes are referred to as oversize because the cylinders are bigger than standard.

forgot all about this sorry mate.
Big end bearings are £25+VAT for all sizes and are available in standard, +.25mm and +.5mm undersize only.
Head set is £24+VAT
Bottom end set is £26+VAT
all gaskets are PAYEN so good stuff and prices are correct at the time of writing this.
