Hi everyone,
Time for another check in. Once again I've gone off on a complete tangent and shelved the gearbox for the moment and I'm planning on focusing heavily on the engine. I've brought the whole pile of bits back to my workplace so I can stay and work on it during evenings. At the moment I'm in the process of sorting through all the engine components and fixings so I know what I've got and if there are any bits I've managed to misplace.
I've had a very good quote to have the engine block refaced and rebored out to .040. I will be sending the block off to get this done but first I'm cleaning the whole block myself, perhaps a bit obsessively, for a bit of money saving but mostly personal satisfaction. My evenings at the moment are going round it all with a wire brush drill (not on any of the flat faces of course!!). There probably are quicker ways to clean the block but I'm enjoying doing it by myself in the workshop, so no harm done! Once I'm finished for the night with the cleaning the block gets a soak of WD40 and is wrapped in the bin bag, I don't want rust to come and bite me early on.
I've decided not to go with getting the crankshaft/flywheel balanced as based on the minimal wear on what are standard main bearings that have come out of the engine, I don't deem it to be necessary. I also need to save money where possible! I was caught off guard with the crankshaft and noticed a bit of surface rust coming along on the journals. I've since cleaned them all off, masked each journal and wrapped in a bag, hopefully to keep the rust at bay!
My biggest choices are the moment are where to source new engine parts from as I'm starting to build up a parts list. For now it needs 4 new pistons and at least 3 new tappet slides. I say at least 3 because I've found 3 that are cracked and so won't be going back into the engine. Is it practise to get a complete set of 8 of these though or is it fine to just replaced the damaged 3? The guides and rollers all look to be in good condition so I have no intention of replacing these parts. My mind is getting in a twist trying to look through all the different parts suppliers and deciding which to use for these engine parts. There are massive price gaps between each supplier for pistons and I don't want to make the mistake of just buying the most expensive assuming it is THE best. Is there a go to engine parts supplier or is it just a case of choosing an aftermarket set?
I'm still in the process of sorting through all the parts so will try to keep posted as I'm going along. I've been trying to keep momentum going and have got really hooked on the engine, so hopefully I'll be able to get some real progress done in the coming weeks!
