my engine build

[kevo__]

how do all,
       some of you may of heard from me already as i'm building a road rally car over here in south wales. i've pretty much finished the shell/cage/suspension/blah/blah/etc.... but now i'm starting on the engine side of things. i was busting to go down the 88mm crank and s50 pistons route but tbh i've ruled it out as it's too costly and there's enough power standard anyway for the tight lanes i'll be driving in. anyway even though i'm only doing a standard build i thought it'd be valuable for some of uou to see just exactly what i'm doing to put this standard engine (with a few mods), back together. so here goes stage 1...

          now i've made the decision regarding my engine and i'm gonna build myself a nice fresh m42, lighten the flywheel an stick an e36 318is box on it which combined with my diff (4.45:1 lsd should give me about 100mph flat out and a nice bit of acceleration. i may lighten and balance the thing too depending on how much it costs an i'm looking into getting it setup properly with some sort of chip on a rolling road or poss megasquirting it. in the mean time here's my progress for this evening...

i didn't get a photo of the engine completely assembled but i'm sure you know what that looks like anyhow







not really too much to see generally but it's always nice to get a before and after shot eh? oh below you can see what 100,000 miles does to a bmw block... absolutely nothing! it's still got the factory cross hatching in there so i'm not even gonna glaze bust it.


if any of you have heard about a profile gasket failure and aren't sure what it is heres a picture of a failed one. this thick rubber gasket had corroded away and led to the coolant being lost in quite an awkward place to detect.


the first thing to do once i make a tool for getting the crank bolt out, (bloody tight!!!) is i'll be stripping the block completely and sending it away to make sure it's not cracked and is sound. i've learned this by my mates mistake who has just fully assembled his pug 205 replacing his old cracked block with a nice shiny new cracked block. not a happy man. i'll keep you posted anyway bye for now.

I am in the stages of a rebuild also. Car was purchased from a friend. Did a complete rebuild but didn't replace oil pump. When he started it the pump exploded and took out the housing. I've got the engine tore down and boiled, cylinders are good and have all the parts to start the rebuild. I'm looking for any info that me make the construction smooth. Head has been rebuild and ready to be put back together. I'll try to get pics..
