im no engine builder but the assembly grease seems likes a sales thingy to me which prays on the insecurity of the engine builder.

really like the flush mounted reversing lights. Mint!

video of it running. A before and after would be spoiling us

where the posh people live ;)

new hub is the proper solution but you may get away with using a bearing retainer as made by loctite, similar to threadlocker. The green stuff

bit of a ballache to take it all out in one i would say as you'd have to tip the engine and get it quite high up to get it all out plus the weight of it all would be tough going on your own. Easier to take transfer box and gearbox out as one unit then tackle the engine.

Anyone suggest using an engine sealer, temporarily ?

I'd consider Jotun paints. Used on oil rigs for a reason. As is Corroless purportedly, however Jotun has an excellent 2-part epoxy range. All out the best stuff is the Baltoflke. I used the Hartop which so far has been faultless with a Penguard undercoat for adhesion.

Back to topic... rebuild with SS pistons and new seals. It's what I did and it saved me a bundle of wonga. Easy job.

couldn't it backfeed into the dash lights through the relay etc ? Or did i just spraff a load of sh** lol

bad earth on headlights causing the electrical pixies to back-feed through the indicator earth, path of least resistance. Wouldn't happen with LED,

a case of ass covering, "well sir, we did install a fuse!"

40 amp fuse for a dead short, that might not pull 40 amps but a fuse is a fuse.

DIY video,

Speedi sleeve by SKF will restore the seal lands to new. Easier and cheaper

injectors need checking every 50k or so anyway, may well be overdue, so if they are a bit iffy, then it'll spruce the engine up a fair bit

looks like its randomly missing. Could be injectors, but it could a number of other things too. I'd be testing the injectors because it's easy to do along with testing compression in the cylinders.

does this video help ?
