I bought this motor and every time I start it up it smokes a big cloud of white smoke for a bout 1 minute to 3min. I think its got a bad seal. after the car warms up for a bit about 30min then it starts to over heat. whats the problem is the bad seal causing it to over heat and building air in the cooling system some how? please anything will help guys thanks. Oh also when I drive it it has 0 boost when I give it gas. thanks.

 

it sounds fucked to be honest mate!

Your right, it does sound like a blown coolant seal. Look under the car after its overheated, look for wetness by the left hand wheel (looking from the front)

if so the coolant sela has gone...

 

any one else with suggestions

 

try bigturbo74 hes a local to you.

 

any other suggestions? looking for something more positive than 'gone'?
I respect the positivity!

but it's gone - coolant seal.

 

check ur spark plugs before u start the car on a cold start. check for coolent on the plugs. Does ur coolent light goes on? Sounds like a bad coolent seal. If so then u need a rebiult. white smoke? pray its not the seal and a leaky hose.

 

Bruce we have to take a look at your car, we will have to just make time. Having your Rx-7 down sucks, as mine has been down for the last 5 months.

If it's smoking now at startup, that means that when your car shuts down, and your coolant system depressurizes, it is pushing coolant into one of your housings. There it will sit, until you start the car again, and it will all get burned off, hence the white smoke. Coolant smoke is white, and you can tell from the smell. We can also check your plugs.

If you have having overflowing from your coolant tank near your passenger light, it is also a sign that pressure is leaking from your housing into the coolant chambers, and over pressurizing your coolant system.

You can test this by doing a pressure test on the system. Damian has one of the kits of the proper adaptor, so when we look at your car we can test it that way. It's a pretty decisive test, if you can't hold pressure, and your other connections are good, you have an internal leak.

We can also do the champagne test, do a search under my name if you are looking for info about it. (I should have a video kicking around somewhere)

If your system can't hold pressure very well, smokes at startup, and has bubbles, it is surely a breach between the coolant system and your housing where the combustion takes place. When we finally pulled my turbo's off a few months ago, we found tons of coolant in my rotor housing.

I'm looking everywhere for my pics right now, but I can't find them...

Finally we can test your compression, and if you have an uneven pulse due to a smashed O-ring somewhere, you will have poor compression on one of your pulses on the rotor with the breach.

At this point, having the same issues 5 months ago, and seeing what the inside of my housing looked like... (covered with coolant) I would say 90% you have a bad inner o-ring on one of the housings.

We will try to figure it out asap bro, the more FD's we can get running in the cities, the better! Especially since you have ambitions to run the Rx-6 as well!
