Geo Posted October 30, 2014 Author Share Posted October 30, 2014 (edited) Nothing much to do at the moment im waiting on a bucket load of parts arriving so i can start rebuilding it. today was only a small few wee things, but its these things that really bug me about old cars. So today i sent the Crank Sproket away to get welded Took Delivery of 400 Stainless Allen Key Bolts, these are gona come in very handy. Assembled the lower Sump, bolts are finger tight, still waiting on Gasket sealant, before complete assembly Fitted new bolts, they look so much better than the old crap that was on there Also took Delivery of my Magnetic Sump Bolt So as it stands a few wee things done, once i get mose of my parts its the bottom end fully rebuilt up. I'll get a Spec list with what im running on the first few pages of this thread, with costs Edited October 30, 2014 by Geo (see edit history) Quote Link to comment Share on other sites More sharing options...
gavin.starr Posted October 30, 2014 Share Posted October 30, 2014 Good call with the bolts, I have amassive stash of them I have been collecting over the years. If my mates ever come round for repairs etc... i always replace the bolts for stainless if i have the right size. Good luck with the rest of the build its looking good soo far.

Geo Posted November 2, 2014 Author Share Posted November 2, 2014 So while waiting for parts to arrive, and tubes of sealant and loctite to arrive thought id start about cleaning the carbon for the Pistons. The pistons we're actually in really good condition, then again we're still packed with carbon deposits, so 2hrs later all 6 pistons were nice and cleaned up.

Chris Wilson Posted November 2, 2014 Share Posted November 2, 2014 You aren't reusing the old pistons, surely? I had assumed you were reboring, honing and using new over size pistons? Quote Link to comment Share on other sites More sharing options...
jay200bhp Posted November 9, 2014 Share Posted November 9, 2014 You aren't reusing the old pistons, surely? I had assumed you were reboring, honing and using new over size pistons? This would be first on my list if "refreshing"the motor Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted November 10, 2014 Share Posted November 10, 2014 And before beginning the assembly blow compressed air into every water way, bolt hole & oil way (both directions). And do not hit the new core plugs anywhere but directly on the outer lip when fitting them. Great work so far G. Quote Link to comment Share on other sites More sharing options...

Richie_k83 Posted November 10, 2014 Share Posted November 10, 2014 Yeah i was wondering this too Call me a noob, but why wouldn't honing the block and re using old pistons (with new rings) work? Quote Link to comment Share on other sites More sharing options...
Ric Posted November 11, 2014 Share Posted November 11, 2014 Call me a noob, but why wouldn't honing the block and re using old pistons (with new rings) work? With the age of the engines these days, they may not be perfectly round, i'd expect new pistons and a rebore to make sure the bores are perfect. While it's apart, and all that..

Chris Wilson Posted November 11, 2014 Share Posted November 11, 2014 Thermal cycling, skirt and ring land wear, and fatigue stress means these old pistons will not be ideal for even use in a stock engine rebuild. It would be sheer madness to expect them to take kindly to being reused in an engine being prepared for a supposed 700BHP power level. A re-bore, and a plateau hone to size to match each individual forged piston, that's what it should really have. Power is made in the bores and head...

Chris Wilson Posted November 11, 2014 Share Posted November 11, 2014 Cool, do you do that work chris? Or recommend someone who can? I do boring, honing, balancing, valve guide linering and replacing, seat cutting, blah blah. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted November 11, 2014 Share Posted November 11, 2014 Gotcha, so ideally, you would want to check the bore and pistons for ovality and size firstly then? Careful! Not trying to be pedantic, but bores should be round and straight, and pistons oval in plan view and barell shaped in side elevation, in 99% of applications.

Guest Nicholas Posted November 19, 2014 Share Posted November 19, 2014 Geo, as others have mentioned it would be really silly to re-use the old pistons, get some new ones. Quote Link to comment Share on other sites More sharing options...
