Question about 1986 Volvo 760
I made my vw golf mk2 turbo last week, And I've to say I used my twin Weber 40 DCNF 12 to deliver my fuel, so now I've problem with fuel delivery at full throttle, At normal RPM and begging of the boost it works ok, but when RPM goes beyond 6000 my A/F ratio gauge goes to LEAN part and I can feel the car is running out of fuel, This problem starts at second gear and continues on other gears, I also have to say I used the 4bar fuel pump and Adjustable fuel pressure regulator but I can not adjust it to solve this problem, If I change the regulator setting I'll loose the low RPM rev, For more information I've to say My boost is set on 9psi, If you think I've to change the webber settings or main jet size or fuel pump and regulator so please let me know .

no, you shouldnt have to clean it every week. it sounds like your pcv system is clogged. you have to replace the pcv box and hoses. and clean out all of the gunk clogging up the ports in the block. and it is probably a good idea to replace the intake manifold gaskets and the injector seals. also there is a banjo bolt on the bottom of the intake manifold that gets clogged up so clean the banjo bolts and all attached hoses
