So i finally have the head off ater running into a million problems.. stripped bolts..impossible turbo (i ended up cutting the downpipe to get it out.. and even out.. i still cant seperate the elbow from the turbo..).. then went to take the head bolts off.. got to bolt #5.. and rounded the shit out of it lol.. so tried some extractor bits.. involved a little drilling (super scary).. that didnt work.. bought a new set of torx bits.. got the next size up and jammed that shit in.. and finally it crackked free... eveything was smooth there.. got the head off.. and holy shit the hg was in the shittiest shape ive ever seen..

Btw sorry for the shitty pics.. i took them from my phone.

So i gotta clean the shit out of everything.. any pointers? like what u use to clean all the crap out of everything? i was thinking of using gasoline lol. and also.. what should i stuff into the oil and coolant passages? i dont wanna lose bits of paper towel in there.

Kevin 06-21-2009 03:48 AM

Soo.. anyway.. does anyone have any suggestions to what i should stuff into the oil and coolant channels before i do anything to the gasket surfaces? i dont want crap to fall or get stuff in there.

hey man, sorry no one got back to you on your question. They usually help out a lot. A lil slow lately unfortunately. As for your question I personally used paper towels when I did mine. Then before putting it all back together I used compressed air to make sure there was nothing left in cylinders and what not.

Kevin 06-21-2009 06:19 AM

thanks. you didnt use compressed air in the channels did you? (probably a stupid question LOL)

dannydavi 06-24-2009 04:05 PM

In the cylinders just to get any loose head gasket debris out. As for all the other lil holes, it's hard to cover/stop shit from getting in there. But if any other more advanced Supra owners would chime in they might have a good suggestion for you. I'm a noob when it comes to major repairs like head gaskets... although mine turned out fine for apprx 5 months :( till something in the lower end went out.

Kevin 06-24-2009 04:11 PM

damn lol. How did u prep the block? i'm gonna be using a stock gasket. should i used a scraper on it already but it seems like there's still alot of material.. and i dont wanna scratch the surface

dannydavi 06-24-2009 04:17 PM

yeah it was a pain in the ass for me. Seemed like that shit would never come off. I tried scraping but was getting fed up with it not really working. So i got a cloth scrubby pad thingy for a grinder and went to town.. i figured it was something i could bend with my finger it couldn't possibly tear up my block to bad :P in some spots it worked great and got rid of the gasket. In other spots it just smoothed the gasket out and made it harder to get off lol. Just make sure you take a straight edge to it all when you get it cleaned and make sure it's within the guidelines and you'll be alright.

also i've read in a different post that even after my hg job.. i might run into rod knock very soon? i had milky oil :S soo the oil was contaminated with coolant. before the job i didnt have any knocking though.

dannydavi 06-24-2009 04:23 PM

yeah i didn't have any knock either. But 5 months down the line, my bearings were slipping and sure enough now my Supra is not working. I'm sure that's not super common but it happens.

Kevin 06-24-2009 04:35 PM

Was everything running fine after the gasket job? how about just before the engine siezed? how's u know ur bearings wear slipping? sorry for all the questions.. but now i'm having second thoughts of keeping my supra after my hg job.:(

Remember to use some APR bolt or studs when doing a hg it seems to help out as far as ensuring you get an even better seal from the new hg.

I heard this right before it seized on me.

It ran fine up to that point.

yeah, I used ARP and they worked great, made me feel comfortable torquing them as high as they needed to be. I'll recommend them.

Hey Kev, you'll want to REALLY keep an eye and an ear out for evil noises from the bottom of your engine. Depending on how long you drove it with water and anti-freeze getting into the oil you could have some real damage to the bearing surfaces down there, crank and/or rods. If you're not interested in dropping the oil pan and checking your bearings you at least need to make SURE you run good clean oil in that engine, with one extra quart thrown in for good measure (won't hurt your engine at all, consider it insurance).

Change the oil before you crank the engine after your repairs with a good 30w HD oil and filter. Play around in the dumped oil and see if you find any discernable metal shaving or (worse) chunks in it. Pull your EFI fuse and turn the engine over until you get good oil pressure. Then put the fuse back in and crank her up. Run her only a day or so (and NOT hard driving, don't push the engine yet) then change the oil and filter again to make sure you've got all the garbage out of the block. Change the oil again after a couple of weeks, again keeping an eye out for visible metal shavings in the oil. Might not change anything in the end, but that'll help reduce the chance of RK showing up right after the HG replacement.

Also, if the engine overheated at all you'll want to have the head checked to be sure it isn't warped and have it shaved if it is. Otherwise your new HG will be a complete waste of time, money, and effort as it will blow in no time flat.
