Overheated engine repair

Overheated engine repair

Postby hotrodmike [OP] » June 19th 2017, 4:19am

Hi There Everyone,So about 2 years ago I overheated my 89 Astro van,and its been sitting ever since,i Took it To The local shop a year ago,and They did a system pressure Test on The engine,They Told me after doing The Test,That it could be any number of gasgets,or seals may be leaking,and unless They were To get into The engine,it may either be a head gasget leak,or a crack in The head,and I would be looking at over 3 grand for The work,Yea RIGHT!! I don't Think So!! LOL So I'm Thinking They did Tell me To steam clean The engine,To see were any leaks may be coming from,and That's all good,but I'm Thinking about just getting a complete gasget kit,and starting with The head gasgets,and going from There.The van starts right up every Time I go To Test it every month since its been sitting,i have heard That These 4.3 engines are an Awesome Stong engine,and worth investing in,So with That being said,i Would So Appreciate ANY,or ALL SUGGESTIONS To help me get my Astro Van back on The Road.Thank You!!

either get the following done or do it yourself: compression test, cooling system pressure test and possibly a exhaust gas test this will tell you if you messed anything up or not. But first start it let it warm a few minutes then give it throttle gradualy towith the dog house off to listen for any sort of bearing rattling or knocking, if you hear any of these noises the engine is most likely junk and not much more then that. How far are you from Seattle? Get back to us with answers, You may be better off with a new or used replacement. Mark

If it runs right don't smoke and don't make bad noises knocking etc. Get a top end gasket set. while the heads are off look for clean cylinders. No carbon means it is getting water in it. Easy to trace. if it isn't a cracked head put it back together and good to go.

It is alot easier to see if it is alright once you can inspect individual parts once you have cleaned them. Leaking gaskets are obvious. The sealing portion that should be between metal surfaces. Block and head or intake and head. It is wet and black looking. It should be dry.

If you got it hot enough to warp it a little you think. Spray on some copperseal gasket sealer and torque it down a little extra. It be just fine.
