1986 mustang lx 3.8l


Asked by Jun 11, 2013 at 07:10 PM about the 1986 Ford Mustang LX Convertible

Question type: Maintenance & Repair

This is the second question i have asked concerning the white smoke under load on this vehicle.I appreciate the previous answers but I tried all the tests that where offered
and none proved to be the problem.I noticed after replacing the fuel pressure regulator
that the idle was improved but their was a liquid coming out of the tailpipe.
There is no smoke at idle but when rpms are increased the white smoke starts.
I have done a compression test,coolant test, and every other thing that has been
suggested but it still smokes at higher rpms.Please help.

Automatic pr standard tranny?


if it's automatic check to see if tranny fluid is low could be tranny modulator. easiest way to check is jack up car follow vacuume line coming from intake down to tranny. while car is running pull vacuume line off of modulator. if bad she should be spitting fluid. [note if modulator is bad will give engine a skip do to tranny fluid fouling out plugs]. just be carefull when you pull out modulator seeing thier is a pin that goes into the center about 1 1/2 to 2 inches[do not loose and has to be put back in]

Has anyone asked if the right amount of oil is in. If too much it will smoke.I've seen it done.my friend is stupid and put oil in without draining first. He had to drive it to burn off the smoke.
