Baggedrb20

Hi guys, have an r32 rb20det swapped into my mazda b2000 - have had it swapped and running for many years. Has the following mods; front mount intercooler, 555cc injectors, wastespark setup, tomei fpr (recently brought as my old one shat itself?) Gt35 turbo, link g4+ atom, megasquirt ignitor, powertune digital dash... A month ago i took it for a drive, went and put some gas in then about 1 minute down the road it died, tried anything i could on side of road but battery died so ended up towing home to see if i could find the problem Bit of problem solving, had spark, squirt some fluid in the intake and could get it to start that way only to find out my aftermarket fuel pressure reg gauge the needle was pointing the other way like it had blown up? Removed the fpr and just joined the fuel lines together and fired right up. So got a new fuel regulator but this one as soon as i turned the key the pressure shoots up to 8 on the gauge but when cranking drops down to 5 managed to get it to run tho so took for another drive but as soon as i turned of truck it wouldnt start. So now im trying to figure this time why wont go, have tried taking out the fpr again but no go this time, fluid in intake manages to get a couple of fires, have taken out crank sensor and spun around to hear clicks from injectors has spark , fuel coming through the line to. Could it possibly be that my injectors have gunked up that they now need a clean preventing it to fire as it is kind of my last solution? Many thanks in advance. James

Hi guys, first time using forums have been reading abit on different ones but just want to clarify it in my words. From New Zealand, have rb20 in my 88 bagged ford courier, is a rb20de+t with the goodies and has a link ecu.. will do a bit of a build thread at some point. Anyway as i am currently in the test/tune stage of things i have noticed a bit of an oil leak coming from the left (exhaust) side of engine at front. I have recently replaced cam seals and crank seals before i installed engine so im goj g to the fact that the leak is from inbetween head and block. Have done a compression test and was the same overall hot and cold. Could this problem be fixed by retorquing down head bolts? If so torque to 94? Would i have to drain oil in order to take of cam covers? Any other possibilities that it could be? Dont want to have to replace headgasket if i dont have to. Cheers James
