Sick of Smoky startup - can I change valve seals with heads ON THE CAR?

[BODYMAN]

Considering you have a 03 300A, It is very likely it is valve seals, I had them go bad on my 1st 03 early build, Not a simple job either.

You have to remove the PCV to run a breather like that as you will otherwise draw in unmetered air into the engine. If you remove the PCV you need some other type of crankcase ventilation, a road draft tube or a vacuum pump.

Chevyguy,
I'm with you on this but there was some discussion earlier about PCV air not being 'metered air'. I say it is, others say no. My logic tells me that if it's not metered air when it goes back to the engine a 2nd time, then it should go through the MAF. It does not and therefore has already been accounted for by the computer.

On a completely different subject - I thought 300A's were ONLY the early 2003 cars... With adjustable pedals, dash clock, pouch on front of seat, no traction control, no heated seats... you say your '04 is a 300A but it has heated seats. Can it be a 300A? I could be wrong but I don't think it's an A.

[Blackmobile]

IIRC 300A were made in 2003, then part way through manufacturing they started making 300B. Then in 2004, all MM were 300A

[Ozz]

Ahhhh.... I didn't know that. You learn something new every day I guess...

[Blackmobile]

I still miss the seat pockets that aren't in my 04 300A. I always drop my wallet on the floor.

I'd trade my seats with pockets for ones with heat any day...
I bet you don't get much use out of bun warmers in south Fla so I can see why you'd want pockets back.

I'd don't have pockets or heat on mine.

Well , that's not right... I always thought it was a trade off - lose pockets, clock, etc and get heated seats and traction control.
Must have been an option later on.
I don't think there were any options on the 300A's in '03.

OK looks like PVC/crankcase air is definitely metered. So some variation of closed filtration is the way to go.

Seems oil airation may be causing the problem. Mine was so day and night because of the larger pressure changes/faster revs/higher power.

Still not ruling out the breather, I will bounce it off of JDM as they are in on this. Ordered the steeda. I'm not always under the hood so the clear bottom will remind me to dump the waste. Hasn't smoked on start in a couple of weeks, but I'm sure it will be back if this isn't the problem. I'll post to this thread post install if the smoking persists.

Thanks for finding that link Odinson, it makes a lot more sense explained there.

HELIX - Crown Vic

The "screw" works for the Mustang and Maruader, and the "helix" works for the CV.

I purchased my 'new' marauder 2 months ago. Even though the 2003A MM has only 25000 miles on it, it had the blue smoke at start-up, multiple times. My 2003B had 76700 miles and never smoked. I purchased the breather and the start-up smoke has not yet re-occurred in the last few weeks.

Can someone elaborate on the wrong instructions for Trilogy or point me to a thread? I have a trilogy install and get the puff of blue smoke on startup. Going to likely install the Steeda PCV filter, but want to make sure my install is correct to begin with.
