    Toyota 2GR-FE tapping valve train

    Has any concensus been reached on any fixes to a tappy valve train in the 2GR? I understand they are not adjustable due to hydraulic lifters. Thank you.

    Toyota 3.5 2GR-FE oil

    What do you recommend for normal or extended OCI? If it's a "quiet" oil that might be a bonus due to this engines known tappy valvetrain.

    Red Line MTF and ATF suitable for long drain interval?

    I keep reading motor oil threads where red line motor oil is not able to run "long" drain intervals based on UOA evidence. Something about the esters oxidizing maybe? I have been a fan of Redlines MT-90 and MTF for a good while, and never considered a UOA because I figured it was one of the...

    Advice: Any advantage to motorcycle oil in ZTR hydrostats?

    For example, a SJ rated 20w-50 vs a SN rated 20w-50. Do hydrostats benefit more from one set of additive levels vs the other? The reason I ask, is I recall exmark coming out with their own ZTR hydrostatic oil with "increased zinc" which is either marketing, or beefed up zinc provides better...

    What oil offers best protection for Hydrostat pumps/motors?

    Greetings, Some of the hydrostat systems I service call for a 20w-50 motor oil instead of a true hydraulic oil or even UTF. My question, is what attributes should one look for in a 20w-50 for best protection? Do differences in friction modifier levels or ZDDP levels matter more? The two...

    Need Honda TPMS relearn/programming tool recommendation

    Hello, I have an issue with an 07 CRV where my winter tires with TPMS sensors turn on my TPMS light. ABS and everything else works fine, but I understand I need to read the TPMS codes from tires and program it into the ECM on Honda and most Asian vehicles. Please recommend me a tool that works...

    2021 Honda CR-V Hybrid AWD Touring: Thoughts?

    Any thoughts on the CRV Hybrid? I am happy to see it comes with a NA 2.0 instead of the dreaded 1.5 turbo. Also, apparently this comes with an interesting direct drive transmission instead of CVT? Information seems sparse on the details when attempting so search. Thank you

    Which SN+ or SP XW-30s are actual 30 weights currently?

    I have been reading about some 30 weight oils that have trended toward being thick 20 weights. Which are still true 30 weights?

    Are Honda 1.5 Turbos still diluting oil in 2020?

    I know most direct injection engines suffer from some amount of fuel in the oil, but has this been fixed and now GTG on the newer Hondas?

    Rotella T6 15w-40 going to be staying on shelves?

    Just noticed it was on clearance at TSC and the one jug they had was $19. Last week Walmart only had two jugs. Not meaning to start a rumor or anything, but I figured by now this would be a well stocked item like the endless T4 and T5 varieties that always seem to be in stock. Maybe people are...

    At what point will oil consumption cause oil pump starvation?

    Theoretically, in a typical oil sump designed internal combustion engine, when might the oil pickup start to pick up air because the oil level got too low? For example an inline 4 with a 4 quart capacity driving on a flat and level road with no hills to cause oil to pool away from the oil...

    Rotella full syn T6 15w-40 for 37hp Vanguard twin?

    This seems like it would be an ideal oil for air-cooled OPE. About the biggest detraction I have seen compared to other HDEOs is that VOAs show a slight decrease in ZDDP compared to say T5. Vanguard recommends their own 15w-50 for all temps down to 20 F. To ensure more than adequate ZDDP I...

    Knights muzzle loaders?

    Which one would you choose and why? Torn between 50 and 45, and what's the diff between the bare primer models and the "full plastic shell"? Can you swab bore by simply removing the bolt like a centerfire? Thanks, not new to muzzleloading, but new to inlines...

    Best propane fireplace insert?

    I currently have a decent insert running off of a 250 outdoor propane tank (ventless). It produces decent heat, though the blower is loud, and there is a definite smell from running it that fills my house even after only a few minutes. I am interested in reducing the smell, increasing...

    Re-torquing head bolts as preventative maintenance

    The googles didn't bring much up unfortunately except don't mess with aluminum heads. I have an old Allis tractor I am currently doing a valve tappet adjustment on and wondered if it may be a good idea to check the head bolt (most are bolts, but 4 are studs) since I have the valve cover and...
