Hi Newbie here,
I have a '92 Rocky bought it about 6 months ago, since then I had coolant loss, spitting exhaust on startup etc etc. Had the gaskets, cylinder head, glow plugs, timing belt + tensioner/idler bearings replaced + full service all seemed fine. Yesterday for the first time I did a proper long run on the motorway, and noticed when I stopped and the engine was idling that it was producing a lot of white smoke but with quite an acrid smell as well. It doesn't appear to be losing any coolant or oil at the moment (or have any coolant/oil mixing or bubbles in expansion tank) but I realise it may be too soon to tell. I am familiar with the usual coolant in the chamber kind of smoke as I had lots of it before the head/gasket were replaced! Although I'm not ruling it out entirely until doing a compression check when its hot, This doesn't feel like that + it's starting fine with no white smoke, just a puff of black when it first fires then no smoke after that. Is there anything else that would cause this smoking only at idle once the engine is hot? any advice would be greatly appreciated...I want to love this jeep but it is testing my patience!!
