uumm pulling engine to replace


Recommended Posts

okay i have an 89 xt-6 one of the valve cover gaskets leaks and it burns about half a quart of 10w-40 about every 1-2 months i drive about 350-500 miles a week so i consider that accetable for a 16 year old engine with 152k on it and yes i change my oil every 3000 miles okay now i am planning to pull the engine to do the gaskets so i can put in new mounts on it and i am planning on having a spare set of heads rebuilt with new valves and delta cams. just as long as i have the engine out. I am looking for input as to what else i should do as long as i have the engine out/apart also what parts stores sell delta cams and to further make myself look dumb for the people in colorado where can i get my heads done right for a good price

one of the most important things to replace - there's an o-ring at the corner of the cam carrier that is metal reinforced. http://www.thepartsbin.com is the only place other than Subaru i've seen that you can get this part. it's only like 2.13 from the dealer...steep for an o-ring but you only need two of them.

Subaru part number: 13089AA010

(same one that's on the EA82 - so the dealer usually has them in stock every time i've been there to pick them up).

 

if you're doing all this work and planning on another 100,000 miles then there is no reason to leave the stock oil pump on there. order a new one (it'll have all new gaskets, seals and pressure sender as well..good stuff) from http://1stsubaruparts.com/ for 143 dollars and some change.

 

of course you'll want to tackle all the cam seals, crank seals, valve stem seals (included in the head job), fuel injector seals, water pump...etc. you'll likely want to get a complete head gasket set so you get all the associated parts you need. the FelPro set is nice just because it has those weird clip-on oil port o-rings that cost like 15 bucks a piece from subaru...and there are 6 of them so you're talking 90 bucks for a couple orings. They are included in the Felpro sets i've gotten but not the Corteco sets. it's almost worth buying the felpro set for all the other gaskets/seals even if you buy Subaru head gaskets (which some people recommend). fel pro set can be had for $150 and includes fuel injector seals, those goofy clip ons that i just mentioned, intake and exhaust gaskets, intake and exhaust valve seals (which you'll need for your heads) and more. so that set is worth it even if you don't use the head gaskets which you can probably sell to someone else for a few dollars. Subaru head gaskets alone run 26.00 (at least that's what i bought them for)...each dealer has different pricing. that 1stsubaruparts i mentioned earlier probably has good pricing on the gaskets though i've never priced them there.

 

there's an awesome aluminum head specialist in my town that does tons of heads, including a good amount of experience with EA82 heads which are basically the same as the XT6. they do a fine job and properly repair all the cracks between the valve seats you see on almost every EA82 and ER27. could probably work something out shipping the heads to me and i'll take them in and work the deal for you, these guys are really good. they ported, polished, resurfaced, cleaned, complete valve job, repaired all the cracks between the valve seats on an EA82 for me for 503.00, not a bad price for all that porting and polishing. i've had them do my XT6 heads, but can't remember the cost. they aren't particularly cheap but have lots of experience with these heads and do a great job, so i'll pay average price for that kind of service. i used to have heads rebuilt at a locally respected high priced place in town that's been around 30 years and they never mentioned the valve seat cracks. i don't go there anymore. not that i think they're bad but i like this aluminum head specialty guys alot.

 

oil pan gasket. get it right, it's tricky to keep it from leaking again if the bolt holds on the oil pan aren't flat. it won't seat the new gasket very well. you can try leveling the pan out....annoying....or covering gasket with a gasket maker.

 

there are some engine reseal, parts list and gasket replacement threads on http://www.xt6.net so search around there for lots of information on different head sets....corteco, Felpro and Subaru OEM options. scott (gravityman here) is having custom made copper gaskets i believe and he's getting them for a reasonable cost. he posted more info at http://www.xt6.net and maybe he'll see this thread here.
