I need some help, i blew the head gasket on my engine (rb 20e) when i pulled off the head the water ports were all eaten away. I purchased a 2nd hand one which was in good condition. every thing is bolted up, now i need some help with setting the timing.

1. how to position the cam and crank, what markings to look for

2. how to position the distributor.

any help would be good, i know i should have just put in a 25 and done the talk, but my funds would not allow that, so for now i just need to get her back on the road.

thanks

quick question, when the new head is being bolted on should the pistons be at tdc?

the reason i am asking is that i bolted on the head and lined up the cam with the required markings, however, the crank only turns 180 degrees and then locks up. as if it was bouncing on a valve. i did not put the pistions at tdc before bolting on the head. could this be the reason?

any help would be good thanks

    • 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
