I'm experienced with these engines and this technique was tough to do (but got it done with a friend). Much respect for you to invent this. Way easier with the engine out of the car, though. Lol.

Yes, not super easy, but handy for when you don't want to tear it down.

Excellent video. I'm in the process of replacing the head gaskets on my 1998 Forester with DOHC and buckets with shims. The machine shop touched up the valves and seats, so obviously I need to re-do the valve lashes. TWO THINGS: First, since the shims are so hard to find these days, and i want to have them as close to ideal thickness as possible, I'm wondering if I can have the machine shop cut down my existing shims (they are almost all too thick now) - I would have him machine the side that sits in the bucket, NOT the side that is in contact with the cam lobe; (2) ONE THING I HAVE FOUND - Do NOT trust your feeler gauges! I have three sets, which I checked with a micrometer before using. One set "Hotop" brand from Ch__a, had one gauge that was off by a full mil (0.001") from what it was marked - marked 11 mils, measured 12 mils, and another that was off by 0.4 mils! So I ended up using the measured thicknesses, and then sometimes combining two gauges in order to get an accurate measurement. Thanks again!

I have successfully used a belt sander to shave down the shims when the proper one couldn't be found, however they are made of a super hard metal and it took quite a while. I'd assume the machine shop could do the same

This was helpful for measuring valve lash in car. Unfortunately mine were totally messed up and I have solid lifters so I guess it's time for a timing belt job as well.

@johnjohnson9827 Жыл бұрын

I was pumping the valve and jam the shim up inside the bucket it's the only way to get that shim out now to take the cam out?

@nealio990 Жыл бұрын

@@johnjohnson9827 if by "shim" you mean the feeler gauge, you should be able to insert it without using force. If you have to use force, it is obviously not the right size feeler gauge. Also helps to make sure there is a film of oil to ensure it goes in smoothly. If you jammed it in there you may have to remove the cam to get it back out.

bit late, but my crazy neighbor did head gaskets with engine in the car, both SOHC and DOHC...so if you can take the heads on in car, you can change cams...I'm sure it is more painful than it even sounds !!

Any tips for compressing the buckets at the back of the engine? I can get the front 3 out easily like you demonstrate. I can't get the furthest back one, my screw driver just slips off the cam-end when I twist. Did you use a different tool for these four?

Nice to see the DOHC featured and good video. My USDM 05 OBXT MT is .14-.24 mm Int, .30-.40 mm Exh. according to the book and the underhood sticker. It has the full buckets. After 170k miles, I'm doing the head gaskets. The Int buckets were all in spec, but the exh were all out of spec - too little clearance. Since the shim buckets only lost a ten thousandth, is this the valve seats wearing down?

@AlanFixedIt 3 жыл бұрын

It's very common for the exhaust clearances to tighten up, and the Ej255 is notorious for burning valves due to the clearances being too tight. They tighten over time as the valve stem itself stretches from heat and spring pressure. Valve seats can also factor in. You will need to measure and then order replacement buckets from Subaru that are the size you need. You may be able to find a machine shop or Subaru specialty shop that has a bucket grinding tool (goodson makes one), this is the method I use for solid buckets, but most people don't have access to one.

@zoomthumpthump 3 жыл бұрын

@@AlanFixedIt That's really interesting that they can be ground to size. I would think that there is the possibility of grinding through the surface hardening, but maybe the metal is already thin enough that they are hardened all the way through.

@AlanFixedIt 3 жыл бұрын

@@zoomthumpthump I should have specified, bucket grinding actually grinds the bottom side (inside) of the bucket. There's a protrusion that the valve contacts, this protrusion can be ground down

I know it's an older video, but does it matter how the bucket is oriented when you're done? like if the notches need to be straight up or...?

It doesn't matter. In fact they will rotate around slightly with the engine running.

LOL. Did the turbo cars spit the shims out? OUCH! Being a motorcycle person, I know that, most Japanese motorcycle, OHC engines, use shim under bucket now a days. Of course, some of the Hondas, they forgot the buckets on the exhaust valves.... but that's a nice little trick. I gotta do some work a a 2005 Forester I own. It needs more than a valve adjustment, if I take the motor out.. 150K it's time.
