pwoens Posted November 25, 2004 Share Posted November 25, 2004 Can I just replace the blown head gasket and then keep driving it??? Assuming the heads not warped of course?? Im sure it depends on how hot everything got also??? Just curious what you absolutely have to do once you blow a head gasket on these 88 ea82t's. thanks Link to comment Share on other sites More sharing options...
WJM Posted November 25, 2004 Share Posted November 25, 2004 Idealy, you want to take the engine out and while its out, replace every gasket on the engine. Have the heads send off ot be presure tested and machined back to trueness....and put it all back together properly, make sure the cooling system in in perfect health, and run Mobil 1 synthetic 10w30 in it, and it will run forever.

stngllhm Posted November 25, 2004 Share Posted November 25, 2004 you can do what ever you want it is just a matter of how soon you want to do it again Link to comment Share on other sites More sharing options...
pwoens Posted November 25, 2004 Author Share Posted November 25, 2004 you can do what ever you want it is just a matter of how soon you want to do it again I plan on pulling the motor and doing atleast the head inspection. What else would you reccomend doing at that point? Rings, bearing, ??????? Thanks Link to comment Share on other sites More sharing options...
stngllhm Posted November 25, 2004 Share Posted November 25, 2004 leave the block alone it is rare for there to be a problem there. all the gaskets like wjm said. and rebuild or replace the oil pump and water pump Link to comment Share on other sites More sharing options...

idosubaru Posted November 25, 2004 Share Posted November 25, 2004 depends on time/money. i think pulling the motor offers little in rewards to effort ratio. i have an engine lift and do it without a problem, but in general i wouldn't say pulling the motor offers anything worthy of the extra time and effort. these 4 cylinders are awesome to work on, you can do the heads in the car and be done with it in no time. the only advantage you have is to replace the rear main oil seal and gasket on the oil separator....along with the transmission stuff if you want. but the oil separator is a very minor issue (though it's dirty and the stock one is basically heavy paper) and the rear main seal rarely has problems (not nearly as much as the front crank seal in my experience). i've pulled a couple 200,000 mile blocks and haven't seen a seep around the rear crank seal. one guy on the xt6 site says they never leak and he never replaces them. that being said, having the motor out is nice, easy access and definetly don't touch the block. pulling the motor and transmission out together is always a nice option, it's very clean and easy to do that way. if you have an auto, it's much easier to seat the torque converter properly with the both out of the car. all you have to do is loosen a couple tranny mount bolts, pull the axles (no bolt) and drop the rear drive shaft if it's AWD (very easy to do). if you wanted to save money and just replace the gaskets then i'd recommend replacing both head gaskets even if only one appears to be leaking. a friend blew a head gasket, i replaced one side because that was the only side gushing coolant. after reassembling after replacing one gasket, turned out the other side was leaking as well...i guess due to overheating. both heads were fine. valve job, valve seals, test and mill head, replace gaskets and you'll be driving a long time. make sure the heads and block surfaces are CLEAN. and the head bolt holes as well.

Ratty2Austin Posted November 25, 2004 Share Posted November 25, 2004 if your interested, I can give you a deal on a service... I could come and reseal your engine for you, I have a "set price special" on headgasket jobs for board members- 200 bucks (labor) for ea81, 300 for ea82 (tbelts and camboxes take longer) and I could do all your gaskets too if you like... parts cost is extra... (reseal kit is usually about 150 to 170 for ea82T, which I could aslo get OEM from my work) if your interested, let me know- I can get it done in a day assuming the heads are not damaged (if its only a reseal) and the weather is good... I have done my own reseal in my 86 XT turbo- works quite well! doesnt leak a drop and holds up to my excessive use of boosting and I also have done (ea81) headgaskets for EdRach too- which I belive worked well... I noticed you live in spokane though... fuel cost? (30mpg in my XT) hmm... Link to comment Share on other sites More sharing options...
