    Compression testing process

    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...

    Additive for oil consumption - Toyota 1AR-FE

    My Toyota 2.7L 1AR engine uses a lot of oil. Like a quart per 500 miles or worse. It runs very well, is smooth, and gets good mileage. I know this engine has the issue with low-tension piston rings so I've assumed this is consumption past the rings but I suppose I can't rule out valve stem...

    Structural adhesive failure in roof?

    The roof on my 99 4Runner has a few cross braces that are structurally adhered to the roof panel and to the side pillars. There is an interior noise that I have had for some time now and is getting worse. I popped some of the plastic paneling off and confirmed it is coming from one of these...

    MT Fluid for problem Ford (ATF spec)

    5-speed manual in a late 90's Ford Explorer. Spec'ed fluid is ATF. Did a drain fill with Maxlife and it's OK but a couple synchros are clearly worn. In a Toyota trans I'd try adding some Redline Shockproof but I'm not sure what magic friction modifiers would be best to try in this case. GM...

    School me on Toyota Flywheels

    Running the original Toyota flywheel on my 99 4Runner with 280k+. The previous owner had the dealer change the clutch at 180k and I figure they did not resurface the flywheel because it chatters when cold if I its engaged smoothly -- if I let it slip a bit it does not chatter. I am making plans...

    3RZ 280k - What I've learned from 9 oil reports

    Oil analysis reports from the engine's life 230k - 280k I've switched back and forth between 5W-40 diesel oils and RGT 5W-30 The way I am summarizing the data is to normalize the wear metals by 1000 miles of use on the oil. I then averaged the Fe and Al between RGT and the diesel oils...

    3RZ 265k - UOA History Summary

    Just finished the 7th UOA on my higher mileage 3RZ (Toyota 2.7L 4 cylinder). This truck is driven pretty hard as it is often loaded down with gear and people and sent out into the woods. But I make up for it by overmaintaining it, hence the 5k OCI on full synth products. But I do change the...

    Blending 90 and 140?

    Hey guys, I sometimes use a 50/50 blend of 75W-90 and 75W-140 in my rear diff as an attempt to hit a ~110 in the brand I like to use. It occurred to me today that perhaps a "blended weight" is not the same. Here's what I mean: a given oil may have a distribution of oil molecule lengths with a...

    3RZ 235k miles Rotella 5W-40 5k interval

    Hey folks, First oil analysis on my 99 4Runner with 3RZ-FE engine. At the time of the oil change the engine oil (Rotella 5W-40 CJ-4) had about 5000 miles on it and the engine had 235k. Everything looks good except for the 180ppm of sodium. The lab states that they think it comes from the oil...

    I've been using Bosch Distance Plus (BD+) oil filters on my cars for a while. They seem to be extremely well made. I usually run them about 10-15,000 miles (2 oil changes). Are these filters getting much love here? Anyone running them?

    70's Dodge 318 Transmission Fluid

    Asking this question on behalf of a friend with an early 70's Winnebago with a Dodge 318. I don't know the technical name for the automatic transmission it has, but the manual calls for Dexron (I guess you'd call this Dex I). What would be an appropriate modern fluid to replace this with?
