Is my block scrap?
Turbo Mini Forums

I'm rebuilding my engine and noticed that the block has a piece broken off on the oil filter head mount. Can I fill it with jb weld and tap the thread or is it new block time?

Timecert(much stronger than a helicoil in this situation) and a little silicone to help it seal and itll be fine. IMHO, curious what others say. or tap the threads right down and put a stud in there. and again a little silicone to seal it. definitely wouldnt waste time with any 2-part chemical metal.

if your up to it you could also build it up with a MIG/TIG and re machine/tap.

infact id certainly build up atleast the inside edge with weld so it seals.

I would clean every thing up so its oil free, put a ligtly oiled bolt in there, spadge some devcon steel putty in, an when its dry undo the bolt out and draw file it flush. make sure you plug that oil way though so no shit goies up it....

or better still, if the engine is out, just get it milled down till its flat, theres enough meat there, but you might need to add a plate to bring the oil filter housing back to where it was.

I think the best solution is as Joe says, a suitably large cutter in the mill and face that down till you get to a faced surface again. Then as said a spacer with gaskets both sides to bring it back out if required. Devcon is surprisingly good stuff but with pressurised oil trying to get behind it I'm not sure how well it would last here.

I think you will be fine with some metal putty stuff in there.

That would be easy to machine, so NO, it is not scrap...

Grand, cheers for that. Slight over reaction so I'll pop on down to a shop on Monday and get it milled back.

Ta everyone

Devcon or belzona are great products if the prep work is done correctly, ive used it many a time at work (offshore) in refacing many different sizes of flanges and relining pipework of different pressures, temperatures and products running through it.

Just an update. After everyone gave me good advice to get it milled, I decided to do the opposite and fill it with jb weld. Sorry. I oiled up a bolt , screwed it in and filled around it. Filed it back and it seems good and solid. I'll see how it holds up.

Not everyone told you to get it milled! :)

Very true lol, it seems have stuck very well so I'm hopeful of it being a good mend

yeah that looks fine,

Cheers Joe, your method worked grand. I nearly bought some devcon that is on eBay for £20 a tub as it's out of date but I chickened out. If anyone else dares it does seem fairly bargainous

good good.

I'd put money on the issue being due to the stud not being screwed in far enough or the bolt being too short.

also I alwys like to use the later gasket as its much sturdier, but you will need the right housing... or a nice billet one.

as joe said

i always use studs much better than bolts as your just putting pulling forces not rotating as well like a bolt

looks like its up to the job all its gota do is stay put till its all tightened up and held together after then i doubt it'll move any
now its bath time get all the junk out

could of got it built up with weld then milled down?

personal that been my move on it.

Weld probably not but braze yes, but then you'd need to fuck around wit the threaded hole probably.
