I Bought A 1982 Ferrari 308 GTSI That Was Sitting For Years which Is A Bad Thing In My Opinion I am trying to get it driving again. I changed all the fluids gear and engine oil shift shaft seals New Bosch brass fuel injectors and seals checked all the spark plug gaps wires put heat shrink tubing on the spark plug extenders. The Ferrari has new Hyper-Flow cats my problem is my 4 Tip Exhaust is Blowing harder on right side. The left side of the exhaust appears to be White steam coming out that smells really rich. Any help guidance would be great Thanks
Your left side is not firing. It's spark, sounds like. Check for electrical connections. Most likely its is a loose plug. The simplest answer is usually the best one. Next, check the coil pack.
This issue has been discussed many times in the 308/328 forum. Yes, the 308s and 328s do that. One exhaust tip seems to have less flow than the other, especially at idle. It's just part of the design of the muffler. It does not mean that one bank is not firing.
I passed on a great 328 when i was looking for a car because of that issue, a few days later I found out its normal but the car had already been sold.
Unfortunate. My 328 does it more pronounced than my 308 did. It has to do with the internal baffling of the muffler and the way the exhaust pipes enter the muffler. Supposedly at normal operating speeds, it equalizes as exhaust pressure builds. But at idle it is fairly lop-sided, one definitely blows stronger than the other, and it is perfectly normal.
