How to check HG leakage???

[LoveTheeSubie]

I know,I know.....Stupid question........

 

Thinking about buying a 85 Brat and I'm looking for all the Advice on how to check for HG leak/damage.

 

The only method I know is to check what Is coming out of the Tail Pipe, Look for White Smoke,Right????? While reving up the Engine????

 

I've worked around cars but nothing like a Engine Overhaul or Tranny Overhaul......I guess I've been Lucky:-p

 

THANKS GUYS, YOU ALL KISS rump roast!!!!!!!!

What makes you suspect the HG? EA81's are not like EJ25's - they don't just blow them because the stars are aligned.

 

As for rebuilding an engine - the head gasket is a GASKET - it's also nothing like rebuilding an engine or tranny. They are simple to change.

If there's reason to suspect the HGs, you have a few simple checks and a few not so simple.

 

Simple:

 

Oil in the coolant/coolant in the oil

Milky "blowby" residue on the oil fill cap. This can also be piston blowby though.(Neither are good)

Bubbles in the coolant res while the engine is running.

Steam pouring out the exhaust.

 

Less simple:

 

Compression test, only really counts if the HGs are really bad.

 

Shop needed:

 

Sniff test the radiator for hydrocarbons.

I didn't know the obvious signs of a Blown HG but,now I know what to look for. Thank you all.

 

Also, what does it mean when a Old Subie(EA81) back fires?? I was looking at a 86 GL Hatchback a while ago and it had this problem.....So, I walked away from the deal.....fearing that it would be a costly repair. Thanks again.

Carb fueling and distributor ignition are notorious for backfire conditions. Usually means issues with the air/fuel ratio and ignition timing.
