1999 Impreza. Looking for a relatively low mile complete head. My car has a 104000 miles on it. Looking for around that mileage. Pretty sure it has a bent valve on that side. Also does it matter if it’s a manual or auto for my search??? The car is a manual though. I was thinking about taking a chance on this?? https://www.ebay.com/itm/1999-2001-...:pGwAAOSwYbdcSQ5q:sc:USPSPriority!55906!US!-1 Anyway it’s my winter beater summer run around car so not looking to spend a ton. Except on head gaskets and head bolts. I’m dumping money into another car so on the old budget.
If it's just a bent valve, a machine shop can probably fix the head for pretty cheap. Don't need to replace head bolts unless they're damaged.
Ok I thought they could only be stretched once. Also I’m in Rochester SE MN. for machining I usually make the drive to the cities. But again trying to make this easier on my pocket. Anyone know of a good shop around this area? And thanks for the reply!
Subaru (factory service manual and techs) reuse them after inspection. I replace them if they're visibly damaged (like from a leaky headgasket), if they measure short/long, or if the motor I'm rebuilding is intended to be used for higher boost applications. But I also use copper sealant on head gaskets, which isn't by the book, so your call/use your best judgment. At the very least, remove them by hand, inspect the threads, clear out the holes, chase the threads as needed, etc... Re: tty/stretch bolts in general. I'm no expert. My understanding though is that subaru's method of using a sequence of torqueing, loosening, then torquing to an angle, when done correctly, as intended to not stretch the bolt beyond its yield point. And agreed with @Chux re: valve and potential valve seat repair.
I’ve only pulled the engine I haven’t had time to break down the motor yet. I was loosing no coolant. I just heard a pop and the head started ticking loud. And running rough. But it’s likely the head gasket did fail because compression was only at 60 on both passenger cylinders .
I've used Dustin at Southern MN auto supply in Rochester. I've had good luck and fair prices. He decked my heads and tested valves for like $150 or so back when I ran engines with only 4 cylinders. For more tricky stuff I go to Dave at Metro Engine services and know several others who do also.
AutoValue/Motor Supply in Austin has done head work for me several times and a few local friends as well. Never had an issue with them. They are usually pretty busy trying to keep up with the dirt track motor work this time of year, but they might be able to fit you in.
Oh yeah, how’d i forget about you Joe!? Also, @blackozone is a SEMN’er as well. He may know someone down that way.
Dustin at Southern Minnesota can handle all your machining, no problem. Plenty of people in the area know his work, and he's plenty familiar with Subarus. For other stuff related to performance engine work, I worked with Corey and some the folks at Baier Engine on the SE side.
Nothing unique about a Subaru clutch compared to anything else. From the pictures, it looks like it's got some meat left. That said, a nice Exedy clutch kit is like $150 on Amazon, and a no-name (mine had Luk stamped all over it...which is a name) ebay one is like $60. If you plan to keep the car for very long, I'd get a new one.
Ok so I’m almost ready to pull the heads. I can see that they r multi layered gaskets and must have been done b4. Driver side had excellent compression. Do I just leave that head on or do I take both off and do both head gaskets?
This is an interference engine right?? I don’t see any marks on the valves or pistons or valves from a collision.
That’s what I thought. Taking heads in today and I ordered my parts. Thanks again for everyone’s help!
