    So i hope everyone enjoys this one. If you do give it a share! Use this pinned post if you can think of anymore differences. Another one i just remembered is the zleh has a shorter dipstick for more oil capacity.

    I would like to add that the LET and LEH conrods are actually different, the LET one has a little oil squirter hole drilled all the way into the bearing which the LEH doenst have because it has proper oil squirters. Also the camshaft sensor plugs are different

    I'm fairly new to the channel (and I'm slowly working my way through all the videos), but I'm really enjoying Aaron's work! I'm gradually converting the rest of the lads in the workshop, and getting them to follow the channel (it's quite amusing to see technicians and engineers in a workshop full of expensive/exotic stuff, huddled around a computer screen, getting excited about a LET or a smokey old CVH!). It's nice to see someone on KZread who actually knows what he's talking about, because let's face it, there's a lot of guys on here who have fancy workshops and snazzy video editing, and it's a case of "all the gear, no idea... " (I wouldn't trust half of them to sweep the garage floor!). When you hear Aaron discussing A/R ratios on turbochargers and surface coatings on engine components, you just instantly know in the back of your mind, that he knows what he's doing! He's a good inspiration for the younger and newer guys, who are interested in getting involved with engine work - it just goes to show that even with a simple set of axle stands and a home garage, you can still do a really good job if you take your time, do your research, pay attention to detail and approach the task with the right mindset. I/We are assuming that Aaron is a "master tech mechanic" or "engineer" of some variety? Keep up the good work fella, we're really enjoying it!

    Pretty sure the black piston skirt coating is molybdenum disulfide, meant to reduce friction massively, its not Nikasil .. Nikasil is on aluminium cylinders to give the aluminium surface a hard plating to stop rings ripping them apart. Coming from the 2stroke mx bike world, when Nikasil plating chips off the cylinder walls and the piston ring grabs the bare aluminium they seize as they grip/dig the aluminium.

How does the thermostat work. With the water-oil cooler, would the thermostat not be open straight from cold to allow the oil to heat up faster?
