Replace Subaru Head Gasket EJ253 - Part 3 of 5
video description
I have 2 questions that maybe i just missed or you didn't clearly explain. First you were clear that an external leak where you are losing coolant implies the Head Gasket which i understand but wouldn't you be leaking oil as well? My 2011 w 120k seems really stained from oil leaks in the back of the head and I am using oil at a quart every 2000 miles or so. But coolant is ok and I thought the coolant openings were close to the cylinders near the center.
Second has to do with the machining required. Do you always automatically send out the heads to get resurfaced or did you do another check to figure that out? Also the problems with the valve guides, did you know that before or was it the machine shop that told you they needed to be replaced?

Hi. Just been watching this and thought to share. I'm living Sydney. I bought an 06 Forester with blown h gaskets for the misses. Cheap because most mechanics here will charge A4000 to replace and even then they'll fit singe filament gaskets. Firstly, by the time I got all the junk off the engine, dismounted and headers off I figured was only bell housing bolt left to pull the engine so I did. Certainly easier than reaching over the side. What I did discover though is that it is possible to fit the wrong head on the wrong side! Only discovered that after I put the engine back in and got to connecting the pipe from the back of the left head to the intake. there was no hole! Bugger. Pulled engine back out and took a punt reused mls head gaskets. I got the heads machined, levelled the block with diamond stone. Did valve grind. Has done 10, 000 K since and all is good. Pretty hard to check block flat in situ. Thx for vid. Your back younger than mine

I bought 100 8-oz. cups and lids and 50 32-oz. cups and lids from Smart and Final. I labeled them VALVE COVER - R, VALVE COVER - L, ALTERNATOR, WATER PUMP, FAN, RADIATOR, and so on. There are plenty of tubs to go around, even for things like SUPERCHARGER FRONT COVER and anything else which might show up.
Sure, it takes a few minutes extra on disassembly, but it has saved hundreds of hours of head-scratching on reassembly over the years.

Worried about the valves when take and putting on heads when changing gaskets. I know where the marks needs to be for TDC, but do you have to put pistons half position in cylinders to keep pistons from touching valves? Or would lining up cam sprockets and crankshaft good enough especially when reinstalling heads?

I did head gaskets when I was a kid, just about I gotta add, on a mid 90's Lincoln town car and I bagged and labeled every nut and bolt I took off, man what a pain, never had I dug into a car that deeply before, but I got it all back together and it even ran right. A proud moment. lol. Thanks for the video.

Formula 88 is perfect for degreasing aluminum heads and blocks. And it's super cheap. Soak them in a few gallons of that stuff for a couple hours, power wash them off and they come out absolutely spotless WITHOUT etching the aluminum. I HIGHLY recommend using that stuff instead of scrubbing for hours.

Still 2 parts to go. Just caught up this 1. Can't help wondering if you have seen the same Sooby since, maybe for another head gasket: ) Cool stuff, comprehensive. You got me looking at Knipex, all sorts, very nice, but can't justify getting one, but might still: )

Eric thanks for sharing your invaluable knowledge as it makes a big difference in getting things done efficiently as well as effectively rather than down the time consuming lane. Did you already post the exact name and make of ALL those special tools? Ill check.
