Hello,

I think my Lounge has a blown head gasket. When I start the engine, I get a ton of white, sweet smelling smoke from the tailpipe. I can't think of any other reason for so much smoke but maybe I'm wrong.

I'm going to try some K-Seal tonight to see if that sorts it out but I'm guessing I'll have to replace the gasket sooner or later.

Has anyone here ever replaced the head gasket on their Fiat? I've changed a bunch on pushrod engines and one OHV motor (Focus) but I'm curious about the "multi-air" thing and whether the head on/off is very different from a standard OHV head?

This video gives an idea of what it looks like inside. Basically it's different than anything else. I can't find a video showing the head removal, but this shows the multi-air. (Obviously, you won't be doing the upgrade they are.)

Yes, it does sound like something (head gasket, etc) is letting water get in the cylinder(s). I don't think the sealer will do it, but worth a shot.

Contrary to some claim, the engine is exactly like any other transverse inline four, and the process is exactly the same as pretty much any other modern FWD cars. Only major difference is the multiair block.

J B hasn't done one - he admits to
'ripping out' an older model fiat engine.
I'm on the tail end of the process.
pm if you like
Thanks dude, yes, I ripped it out as an engineer doing the pre-production, so no, I didn’t replace the head gasket, but I’m very familiar with the process, and I told you how to get to things, you just didn’t like the answer.

No dude, you gave incorrect advice,
The engine has to be pulled to to do the head gasket.
You claimed it did not.

WTF? The engine has to come out to do a head gasket? Based on what I see in the video map linked, it looks like the head bolts are all accessible from the top. What am I missing?

I came back to do an update... somehow missed all this. Thanks for the video, map. Very helpful.

In any case, the K-Seal did the trick. I've put 2,000 miles on it without any more smoke so it must have been a tiny leak!

Hi there,

Did you replace it and did it work?

Hey everyone, sorry I've been MIA.

So this has finally come to a head (pun intended) and it looks like I need to make a decision...

The K-Seal did prevent coolant loss and smoking for about 9 months and it started acting up again. I did another treatment that lasted a few months and then the thermostat failed.

So I flushed and did another treatment which got me through about 2 weeks ago.

The car started throwing all kinds of fits (no power, bucking, missing terribly, etc) Also threw tons of codes (misfires/MAP sensor) and it was due for a service so after an oil change, plugs and coils, MAP sensor and PCV system service: it's blowing white smoke and will barely start/run.

So now I need to decide if this thing is worth the trouble. I don't particularly like driving it (it's fine, just not my thing) and it's probably not worth what it would cost to have it repaired. (And I'm not even a little interested in pulling the motor.)
