Code blue, as in, blue smoke,....psss, please help
My friend wants to buy a gxl 89 s5 na, the only problem is, it blows a little bit of blue smoke during the initial start, after which the blue smoke goes away. I know I know, everyone is probably thinking its blown apexi's, but my friend does not think so, so i'm posting this to see what the rest of u think.
The car is in excellent shape on the inside, it looks just spanky new as if its been taken care of really well. (who knows maybe the engine was or wasnt on the "take care of" list) anyways, the car has 109000 miles on it and is going for a good price. Now, the car starts and all but does not idle, plus it seems to heat up really fast, but from my own experience with rx7's seeing the temp at half way was normal. (Current proud owner of an s4 t2 and "roommates" s5 t2,..,. big rotary fans....however still ametuers) Either way, I felt the exhaust coming out and it seems to sort of "studder" or backfire, (but theres no bang) The car was sitting for a while, so maybe this is just a sitting rotary thing, i know that atleast thats the way its been with my 1st and 2nd gen after a long sit, but not so much with the 2nd though, accually i think not at all with the 2nd.
Finally we havent test driven it yet, but i've reved up the rpm's and it seems strong, even though there is excesive exhaust pressure in my opinion. Maybe thats normal. Plus the air that was coming out seemed to me way too hot, i had to move my hand about 1 1/2 or 2 feet back. Does anyone has anything that they could possibly share or advise on, conserning the blue smoke the exhaust heat and backpressure. Please please reply and let me know. Thanking you in anticipation of your response, Sergei The Saint.

Its probably a leaky oil seal or something. If it goes away at operating temp I wouldnt worry about it. As for excessive flow out the tail pipe, ugh... Ionno. It would get really hot if the car were leaning out.
