It's already off.
I'll give that a go first before I take it all apart. Thanks
I had a vr that was leaking coolant from the timing cover, and when I removed it it had corroded through the cover, so I had to source another one while I was waiting for it to turn up, I deleted the balance Shaft gear and installed a double row timing chain.
After reading a few post they all ended up replacing timing cover gasket, it was also mentioned about intake manifold and thermostat leaking, If I was you since you already about 8min from removing it I would replace it and save time doing it a second time, also replace your thermostat why you at it. Up to you if you want to replace the timing chain.
Looked around the manifold and cant see a leak. Replaced the manifold gasket a couple of years ago so I'll leave that be. Changed the thermostat the same time and cant see leakage there either. Will change the timing cover gasket while I'm almost there I think.
Thanks for everyone's input. Got the cover off, now I have a question. Can I just use degreaser and a brush to clean this area or are there parts I shouldn't spray that onto
Nope just scrap off old gasket carefully without scratch the alloy and if u want you can use wd40 to wipe off the gunk on the inside, use Metho to clean the gasket surface then start putting it back together.
Metho won't clean oil, but brake cleaner will.
If that is sludge on the timing gear then it would be a good time to block off the sump, if it's still attached and give it a clean up with some kero and brush and finish it off with good squirt of brake cleaner, 10 bucks for 4 cans at Repco this week. Be good to measure the chain stretch as well in case it's close to the limit. Only suggesting this as you already have the cover off.
Only use Metho on where the gasket going to sit not the whole thing as it dries fast like brake or part cleaner, only suggested Metho because all most everyone has a bottle in the tool shed.
If you want to clean the backed on oil then I would use turps or diesel as it coats and cleans at the same time to prevent rust. Don't use wire brush just a scrubbing brush and a toothbrush to get in those tight spots, Then to finish a light spray of wd40 and a wipe, make sure to block the sump you don't want crap getting in. If your going to change the chain change the cogs too.
So I got my timing cover gasket in the mail. Has a tear. So I dont have have to wait a week for another (need car for work) can I glue it or would it really be best to get another
Given the messing around to replace it again it's not worth chancing it.
So sealant wouldn't work?
Grey RTV may be ok but I personally would wait.
If you have a auto parts store close get a roll of gasket paper of the same thickness, and use the the ripped one as a template and make a new one.
Didnt even know that was a thing. Top idea, if I can do it correctly that is
Supercheap have them they come in a roll in different thickness just make sure its going to fit first. Or get some high temp RTV and put a smear either side and let it tack off before placing it on.
