Hey all,
this seems to be a common issue and ive read a few posts about it with the 4JB1 running a little rough when its first started on a cold morning and mine seems to be doing just that, even if I let the glow light go out twice or three times even, when i first fire it up it runs like shit for the first few minutes unless i hold the revs around 750 or higher to smooth it out a little, I have just replaced the glow plugs and the old ones were a little wet when I pulled them out did too, is that normal? Ive also had the injectors replaced for new ones too (just to eliminate possibilities) the motor has 171k on it so its not exactly over worked, is this likely to be any major issue or is it just a standard thing for these motors and if it is what is the fix? When its warm it doesnt seem to smoke at all and seems to run smooth enough.
Another question is that im planning to upgrade my turbo and injector pump, now before I go ahead with any performance mods and start upping fuel and boost should i get a compression test done and also have the valve clearances done too? I just want to make sure when I start winding things up its not gonna shit itself after i throw a heap of money at it
