Robert's modified '69 Merc

[Guest]

[69 Merc]

After I learned from this forum that Fram oil filters are crap I changed to a WIX filter.  The WIX filter doesn't have built-in rough areas to help you remove it by hand like the Fram filter did.

Today before I changed my motor oil and filter I bought this Pennzoil adjustable oil filter wrench and it made removing the hot oil filter easy as pie!

Interesting Point Vert.
I'm going back to the track in early Oct and am going to try it without the air cleaner. That test proved no gain on the dyno as well but could well make a difference at the track. I guess the dyno doesn't take wind resistance or engine acceleration into account.

I wouldn't.  What if something you don't want gets in your engine and ruins it?  Or scratches up your bearings which will lower it's life expectancy?

A member here just tried it and it didn't change his times at the track.

Robert. Nothing against you. Or the other member.. I maybe think it was Bobby but don't remember.

But I think far more racers race with an air pan and no filter than then do with a filter. Again. I think. I'm not sure.

Obviously it depends on location too.. But there must be something to it.  

Really?  Most racers don't use an air filter at the track?  IDK but if I ever make it to the track if the Lord blesses me with a better paycheck I'll be using an air filter if my engine is running and the Merc is moving . . .

I think. I could very well be mistaken

This is true most racers don't use them. But if you can get one under the hood its not a bad idea.
Most racers don't leave their motors together long enough to see the damage that can be caused by not running an air cleaner. But if you run at a track that has paved pits the potential for damage is much less. Street/Strip car run a air cleaner, drag only with paved pits you can pass, drag only in a dusty climate with unpaved pits run a air cleaner IMHO.  As long as you run a quality aircleaner that is tall enough there should be almost no performance differance.

MERC are you running a pcv valve? if so its time for a new one

if you're running 2 open breathers and its popping the dipstick tube up, chances are you have too much oil in it or the rings are going away

I have 2 open breathers.

I just installed a crankcase vacuum gauge inside my Merc so while I'm driving I can monitor it.

This morning at WOT I read 1/2psi - 3/4psi of crankcase "blow-by".  That is why my dipstick is popping up and the reason for my oil leaks.  This weekend I'm installing Jeg's header evac on my Merc.  I will report what crankcase vacuum readings it gives me at idle, cruising and at WOT.

so MERC, have you ever thought about a mustangII front suspension setup? its not cheap but you could eliminate the shock towers and fit a BIG ass engine in there

I don't know about that.  More info, experience and links, please!!!

Talking about my Jeg's header evac kit --


Even though the instructions say to weld the part after the collector but close to the merge I wonder if that is ideal because of the scavenging effect?







I wonder if welding in the part a bit further away from the collector's merge point would be better?

just a hunch, but I think that one of the reasons mine doesn't pull so good is it should have been further away from the goilet

What is a "goilet"?

Have you read what yours pulls with a vacuum gauge?  If so how much?

Have to check it with exhaust still but I only got 2" ish at 3000 and basically nothing at idle with headers. I did not mess around with sealing the engine though. I was told it might be a waste of time for this amount of vac.

How are your "breathers" fastened to your V/C's?  I heard that there needs to be a tight fit or the leakage will defeat the vacuum's purpose.
