hey guys, this JUST happenned today when i was driving back home from work. the car felt really heavy, ruff, when in gear. also noticed that the oil pressure bar was just one bar away from 8kg/cm3. i never really take not of the oil pressure, but i do know that the ideal 4kg/cm3. is that correct. is this a potential problem? any ideas whats goin on?

Not sure, but I'd say a big end is on the way out, you have an oil blockage, probably at the big end journals, your motor is in dire need of a rebuild. If you keep driving it you will kill it big time.

But I'd get a second opinion, bl##dy hard to diagnose over the web........

If it was cold and when you first started it up, c'mon, oil pressure will go to 8 and your car will be a bit rough until it warms up. If its happening when its warm, thats a different story.

thats what i thought at first.. but the oil pressure keeps going up to the marking below 8 even when the engine has been running for a while. goin to xspeed on friday to get it chkd out..

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
