Hello fella, had a look at your link, quite impressive to say the least
Thanks for the info and has definitely and finally made sense, ill tell you what it was, I have or had a two spigot filler cap on the 19j im trying to fit and you are telling me to leave the rocker cover breather in situ, I suppose im quite lucky as I do have a couple of 19js engines kicking around(not that I paid any attention to them) and the MOD 12j, you know when you suddenly get that lightbulb feeling, as simple as this, took the rocker cover off with the spigot back and left of the of the cover, and an old pipe that was with one of the other engines and the lightbulb came on, so I followed your plan with the MOD 12j sump and breather equipment and it all seems to look like I know what im talking about, so thanks, I haven't fired her up yet, still waiting on my turbo getting back which should be by the end of next week, so if you don't mind and your interested ill let you know how it all goes, the other thing is am introducing a catch can which im sure your going to say is not needed but belt and braces fella.
The only thing and concern to me is after looking at your link about your rebuild and with all that effort and obvious expense you still found it necessary to still modify the breather system, my old na never had any breathing problems, just a swirl chamber doing its thing flat out at 45mph, a compression test says that the "new 19j" is sound although the fact it has been sat around doing bugger all for 6 months lends to change the head gasket and check the pistons(done almost everything else) once shes up and running, but have these 19js got a big problem with the breathers? Someone has also said the run really hot, is that the case as well? ill leave you alone after this, promise!!! all the best
