A lot of hardcore tractor pull diesel guys run low compression for more power. Supposedly low compression plus lots of boost means more air and fuel and power without pressure getting too high and killing the engine. Might work in your favor as long as it cold starts lol. They use a ton of ether to get the race motors going.
The difference between intentionally building lower compression into an engine and inadvertently losing compression through poorly sealing piston rings is the blow-by. In that case you'd have excessive oil vapor venting from the CCV and also the cumulative contamination of your oil with diesel. Not advantageous.
Hola amigo para mejorar la compresión y evitar temperatura en este motor colocar una junta multilamina metálica de 4mm, es ideal y te da una mejor capacidad de psi y gasoil
I compression tested my 1.6d recently, it had been sitting for over a week and read about 360 for each cylinder (never rebuilt 350k mile motor), I warmed it up and repeated the test and got 415 psi. I had no idea that doing the test while warm would make such a difference. Also that's cool that you have an engineering degree, I'm working on mine right now!
Dang that is a big difference! I imagine the tolerances tighten up quite a bit. Mine was dead cold at the time, it would be interesting to see the difference hot. Best of luck they're not easy 🫠
my 1.6d uses 5qts of oil on a 6 hour highway drive but i blew the head gasket twice from too much boost. I dont run a ccv puck or anything, and the engine has considerably more blowby than it did before the first headgasket went. I assume the oil just gets sucked out of the breather like you said. also Ive played wack a mole with oil leaks on it. fix one and it stays dry for a day or 2 then another seal somewhere else will start. Im currently swapping an MTDI 1.9 Ahu in so i can feel safer traveling long distance. very excited. i made pretty good power with the 1.6d but nothing compared to the TDI
That's dope! Thank you for sharing. 5 qts!!! 💀💀 that's a lot. What kind of boost numbers were you seeing when your head gasket popped? An ahu will be sick
@@OliverFetter yes ARP head studs, on the 2nd headgasket replacement I threw the torque instructions away and torqued them to 150ft lbs and It’s been holding the headgasket. The car will only roll start when cold so I’m probably down a bit on compression but that probably helps the headgasket hold the boost FYI the 1000 mile re-torque of the head nuts is absolutely critical.
Man I was freaking as much as you did when a was looking at this video.. haha felt the panic.. been there done that :) haha
The panic was real 😅😅😅
I've been near to tears during a few projects. That moment when you think something is catastrophically wrong, your stomach drops. Nightmare.
Absolutely the feeling 😅😅
Been there man, so glad it's good. Can't wait to see your time slips!
Hell yeah! Coming soon ☺️

That's a dank suggestion! thank you. I love parallels to other engines

Certainly. Ideally it's an extra thick head gasket & not blow by lol

@@golpawerg4trendline961 gracias! Es una idea buena
Your as mad as a hatter Oliver but in a good way. Great video loved your calculations brilliant keep the videos coming 👍🏻
Thanks dawgie! Yeah this edit was pretty tapped 😂 glad you liked it

@@OliverFetter 30psi the first time, 10psi, the second. I’ve been running 20 psi since then
Have you been using head studs?

@@lowbobcattdi7624 hmmmmmm that's a good call. Thanks for the tip. Wild you were peeling it w studs!!
