Forgot to mention: I also pull the EFI fuse so no fuel gets injected, and unplug something to stop spark if accessible (like unplug the distributor, coils, etc.)

Looking for some advice on best practices for running a compression test. I always do this with the vehicle warm (ie, just after driving and at full operating temp). Pull plugs and then test each cylinder with pedal at WOT. What I am unsure about is this... should I: - Crank the engine over a...

I did 3 K24's in a day last month! They aren't too hard. A super deep socket wrench adjuster thingy like CarLuver linked would have been handy. Also be prepared to bend your shims into a tight J-shape to get them to fit.

Got all 12 individual jugs!

Seems to be working. My order was 12 jugs in total. One of them has arrived and the order is now updated to 11 items remaining. The 1 delivered item is shown as $8.66 price. Thanks for the tip, you guys!

It let me order 4, still showed as 3-pack in the order summary. Fingers crossed, but breath not held ;)

Same balljoint as what's on my 4Runner. Yes, the spec is 103 ft-lbf. It's an M16 thread so it's a pretty big taper. Always tighten to find the cotter pin hole, never loosen. Once you have jammed the tapered shaft in a certain amount backing the nut up will only leave a gap -- you really don't...

I don't put tons of miles on this vehicle so I'd rather still change it in the 5k-ish range, even if I keep the filter on for 10k. Just doesn't feel right not touching it at least once a year.

I had to touch up one valve. Here's the lid off: I also checked the compression just out of curiosity. All four cylinders were 180 psi give or take, well above spec.

Changed the oil just before 300k. Things are looking pretty good!

Just did the first oil change after the ring soak. Around 6k miles, maybe 1/4-1/2 quart of consumption at the most. Sounds good to me! I put in some 5w-40 T6 I had on the shelf to see if it will help with the startup rattle. I can't decide if thicker or thinner oil should be what helps :/

I used this same approach on a 2012 Toyota 2.7L. ~150k, was burning a quart of oil per fillup. One piston soak over a 2-day period with Berryman and the consumption is now ZERO. I'm still kind of in disbelief.

Any update to your noise issue? I have a 2.7 with the same problem. I spoke with a local Toyota repair shop (not dealership) and the tech said he was very aware of this issue and had performed the repair many times. However, in most cases even replacing the cam gear with the updated design did...

Nope, sorry to disappoint! :) I was reading about Restore and it sounded like there wasn't any harm to add it to a "healthy" engine. Based on what you're saying I'll skip it!

Yeah my only complaint now is that the start-up rattle, typical of these engines, persists. I don't think the rink soak changed it. I may try some Restore (since I have it) and see if it does anything.

We're now up to almost 4000 miles since the ring soak. It has consumed *maybe* a cup of oil. I can just tell that it's a teeny bit lower than where it started. Hope it holds!

The 2.7L in my Sienna has this cold startup rattle too (155k). What I don't know is if this is a noise that will eventually lead to a mechanical failure or if it is truly just an annoyance?

I didn't know if it was going to keep burning, so I put in some Pennzoil 10W-40 HM I had on the shelf. I have some BWM 0W-30 (that someone gave me!) that I may run next, and can invest in some of the 0W-20 that it specs now that it's not using up oil.

@Highboy and others, I owe you guys a beer. Big time! After doing the piston soak we immediately used the van for a family trip. It travelled over 1500 miles, much of it at fast highway speeds. It used ZERO oil. Holy crap. It freaking worked. Before the treatment this kind of trip would have...

So far so good! The engine had from Thurs afternoon to Saturday morning with B12 added every few hours and the crank turned over a couple times. In total I used two cans of B12. All of it drained into the crankcase (except was evaporated and the bit at the end I sucked out of the cylinders) so...
