EA82 Weber Blowing smoke when 4wd

Post by suba88 » Fri Oct 26, 2007 8:16 pm

I have the weber carby on the ea82 and when i go 4wding it randomly blows heaps of smoke out the exhaust, continues for about 10 secs then stops. But it does not do this all the time. i originally thought it had something to do with the angles i had the car on, but then it did it when i was driving on the beach, relatively flat surface. I am sure that it never happened when i had the original carby on the engine. I am thinking that it could have something to do with the size of the air filter(very small) and this causes it to suck very hard and pick up oil from the crankcase breather hoses???

any advice would be great.. checked oil after the trip and it was down a little bit.

cheers paul

so wt colour is it?

white means coolant (water)
grey means excess fuel (running rich)
blueish kinda colour means oil.

yeh it is very cloudy white smoke. i just did the head gaskets on this engine so i'm not sure what it could be.

yeah ... but mine did it all the time ... well i guess there were an intermittant 10 seconds when it didnt blow smoke .. but only occasionaly.

that engine built up so much crankcase pressure it would pump 5lt of oil into the air filter box no worries .. only solution was to connect the pcv to a drain .. or just not put any more than 1lt of oil into it.. i tried both and the damm engine still wouldnt die.

only other thing i can possibly think of is that when i installed the weber you have to blank off(remove) a little air pump that is located infront of dizzy and a pipe that comes from the crancase somewhere. if anyone can tell me what this did that could be some help.

sorry its hard to explain what i'm talking about.

yeh heads have been machined. old engine did the same smoke blowing trick and then that one actually blew a headgasket, so i got the top end done, and then the engine siezed due to other circumstances. long story, but anyway i bought an $80 engine and while i had it out the car i recond the top end, using the heads that had just been machined week earlier. But considering the oil level dropped after the 4wd trip i'm thinking oil related. I cant work where else water could be burning.

maybe it is infact burning oil.

take more notice of the smoke it may have a slightly unnoticable blue tinge to it meaning oil.
culd be rings if so. i wuld think valve stem seals are alright if u reconned the top.
