Engine/Transmission (1994 - 1998) What causes all the smoke when it is cold??

[JBrookshire]

I just put in a new rebuilt motor in my truck this summer. Now that it is cold out and when I dont have it pluged in when I start it it smokes like there is a forest fire. I have 370 inj, marine pistons,28deg of timing,191 dv's is it just the combo with the cold weather???? It will still smoke a little bit after warmed up but when first started up after eight hours not being pluged in it looks like a steam ship. The guys at work keep asking me why it does that and I have no good answer for them. The grid heater is working to. Thanks Justin

All the above contributes to it. Low compression from the marine pistons, greatly advanced timing, big DVs, and injectors not known for fine fuel atomization is a recipe for lots of blue smoke in the morning. It's one of the drawbacks to building a motor with these parts. Switching out to EDM injectors and bringing the timing back to 18* or so would definitely help.

Ive got 370s, marine pistons, #10 FF, 191s and 16 degrees of timing, and at 11 degrees outside temp, it blows one puff of smoke when it first cracks off... ... then it doesnt smoke again (till I lay into it of course) Its a light puff of white smoke when it initially does it. Oh, and I dont have the grid heaters hooked up either.

I'd like to see that pic also! Mine is 15. 5 compression, EDM's, 21 degrees timing... . blah, blah! She's a little smoky at work after sitting all day! In the morning it's not too awful bad if you run the block heater for 4-5 hours.

Mine does the same. Smokes and runs like crap until I get some heat in it. I have a similair setup and Im just wondering how it runs when its cold. I cant get the thing up to a decent speed until it warms up. Just curious what others experiences have been.



Thanks,

[JBrookshire]

Thanks..

Thanks forrest for resizeing them pics. If u dont mind me asking, how did u do that???. So is that a normal amount of smoke??? That was after sitting 8 hours at work at 20/30deg weather. All this smoke has all most made me put a stack on it so it is not bothering people. Some people knows what that means and alot of people think u have some issues with ur truck, but o'well.

Howdy Justin.



To resize, I right click on the picture & select Edit.



Once in Microsoft Paint, you need to click on "Image", then "Attributes". In order to post, the #'s can't be over 500. So then you click on Image, then Stretch/Skew & scale the picture down. I did these about 70 percent, in both directions. It's a trial & error thing to keep scaling down till you get 500 or less on one of the #'s.





Oh ... In answer to your question, is this normal, no. Same temps, I don't smoke anything like that.
