Just a quick question. What effect would it have on the running of the enigne if the two breather hoses on the top right hand side of the rocker were blocked? ________________________________________ Peugeot 306 GTi 6BMW 320 td compact M-sport 1967 Mini Cooper 1990 Jaguar XJR 4.0 |

Cool that would be fun to see! what about if there was a partial blockage? could it cause idle/rev faults similar to those from a failing MAP/ICV?________________________________________ Peugeot 306 GTi 6BMW 320 td compact M-sport 1967 Mini Cooper 1990 Jaguar XJR 4.0 |

Highly likely..The rocker breather system is there to do 2 jobs. Remove oil and water from the hot air at the top of the head and secondly to relieve positive crankcase air pressure iirc ![]() By pulling these gasses from the crankcase it will also prolong the life of your engine oil, which is a nice little bonus ![]() On idle it basically sucks the bad vapours out of the engine so if it is partially blocked it will almost definately be causing issues. Scrap the old pipes and stick a catch tank on there, make sure you plumb it in properly though, many people opt to plug the pipe on the inlet mani but this is actually wrong ![]() |
