Hi everybody. I was racing in France this weekend!! I loss in the final versus a 71 GS 455, something that you not see often over here as there are really not much Buick lover over here. But people noticed that my Buick 350 was smoking blue mostly on the left side and, only on the top end. At idle and on normal driving condition no smoke at all. On my last run last year, I was using nitrous and blow the header gasket (went sideway and rev to 6200 on the start.... KABOUM). I didnt use nitrous this time, as I was afraid to harm the engine and worsening the problem. What could be causing this problem? Ring? Valve? I normally pass the line at about 6000 RPM When I pass at 5000 RPM, there is almost no smoke, but still some. Thank to help me David
Well, blue smoke indicates burning oil. First thing to check would be valvestem seals. Then maybe try a bottle of "Smoke Be Gone" or some other "smoke stopping" oil additive. This can help diagnose a problem but not a permanent fix.
look inside your modulator valve's hose and make sure you aint sucking tranny fluid into the motor from a broken/leaky mod diaphram. should be dry inside and NOT smell like tranny fluid. tranny fluid smoke is blue. shows the most under high manifold vacuum situations.
tranny fluid smoke is white I thought.. Most commonly associated with a possible blown head gasket...white smoke.
Any "oil" makes "bluish white" smoke. Coolant makes "pure white" smoke. Extra fuel makes "black" smoke. The odor of the smoke can also help identify it.
Hi Belgium Buick friend! There are sure Buick lovers over here (including Holland). How about a numb## 71 GS Stage1 (Freemont, CA assembled!) or a num## 71 Riv GS and 73 Riv GS All pure stock, youre not alone buddy! But you have to find us in the north part of Holland!
BirdDog is right on how to identify the different kinds of smoke. No doubt about that. As an alternative You just drive on and when the car breakes down, you simply check the oil, water and trannyfluid and then you know what it is you've been burning, 'cause it's not there anymore.....just kidding ;o) I also agree with David from Belgium: there are not many Buick-lovers on this side of the Atlantic, but I am one of them!!!
