Head gasket/welch plugs

Post by Vortex75 » Thu May 15, 2014 4:05 pm

Hi guys, looks like one of my head gaskets is gone or a whelch plug has shit itself. I have water in my oil, bubbling rad, white smoke out the exhaust and a strange rattle/tap in my engine. It's a EA82T, exactly what am I need to get to change the head gaskets apart from the head and inlet gaskets. Never worked on these engines, I've done plenty of Holden straight sixes which are easy compared to the EA82T.
Thanks in advance
Canny

Hopefully it is just head gaskets or a welch plug! The EA82T is quite notorious for cracked heads - especially if they are overheated a few times.

I would contact Frog as there are quite a number of seals you might as well replace while doing the heads. The reinforced O rings for both the cam cases and the seals for the camshafts would be a start.

Just drove a clapped out ea82t from Melbourne to alice spring with the same symptoms, was also running very hot when left Melbourne, by the time I got to Nhill car was running great.placed resone???I think it was called into radiator, it is copper block seal. also tapping noise(lifters due to water in oil), this has also gone. got hot 400km from Alice removed thermostat as it stuck from this product, then ran cool again.
try this product as it proved to work well over thousands of km's, allows time to save up for a rebuild.

Wow, you made it ! All sorts of wonder stuff people swear by. Seal Up by Car Go ? at SCA is another a bottle of clear liquid with copper coloured 'sediment' at the bottom.

Glad to hear you made it - I'd been wondering too!

Canny, I've worked on old holden red 6's as well - then went to the EA82. If you can work on a holden red, can learn some new things and you're observant I reckon you'll be fine with the EA82...

Cheers

Yeah, that'd be good. Just going to have to bite the bullet and give it a go.

SCA degreaser first, under, over, beside it. Wash and polish exterior ....

And before you pull this beast apart - get the timing belt covers off to familiarise youself with position of dizzy, rotor in relation to timing marks on flywheel, the cam wheels timing marks and holes, noting one is up, while other is down. Take pics and save them to something safe like Cannysrebuildpics@geemail.com so you can retrieve them.

Thanks mate, I'll be taking heaps of pics. Going to have to get a few more tools yet. And my car is in a carport and the weather is turning shit down here so that might slow me up too.
