You remember-fill step at head/intake juncture, gasket with R/S and Mariachi's home-brew grease-did I overlook your results or are you hoping to skulk away into the night??? Some guys gave their best advice to help you.

Still waiting on the OG grease - Elmariachi hasn't gotten it yet from the guy he bought it from, so hasn't sent it. No rush for me though, LOTS of visitors in the last few weeks and busy work schedule, so no time with the cobra unfortunately.

Don't worry, I'll post when I get it done and report back if the super-goo grease does the trick. I did decide to say with the felpro blue stripe gaskets by the way.

Screw that bum Elmariachi.

Here, use the stuff I use, it's great and you can get it off Ebay for $20. Just remember to use it in a well ventilated area.

Screw this guy with his toxic blend and go buy my Kendall axle grease for $2.49 and be done with it. Tastes good too.

Don't look for Marichi. He's on a secret mission for the State Department to drink up all the Mexican beer in Texas and convert it to urine.

Anything that is basically poison will always work better than something that is safe. And I take comfort in the fact that Dow warns you right there on the label that if you breathe the stuff you will go to sleep.

Which is probably why your lethargic 42-er8 engine makes 342 HP.

Gosh Chas, and I've been extra nice to you lately.

Hey Max ... as a point of reference on filtration levels , our gear pump division ( the old Borg Warner ) said that 25 micron was acceptable for what we called sleeve bearing pumps , or as others may call them , plain or journal bearing pumps . The only time we needed to get into super low micron levels ( 3 micron absolute ) was with piston pump equipment . I haven`t followed the current thinking for a while , but do remember some "discussions" between engineers about filtration levels getting so low that there was the possibility of removing some of the hydraulic oil additives .... but they were talking about 3 microns and finer . Our engines are very similar to hydraulic pump/motors in the bearing concept ... and requirements . I`m very comfortable with 25 micron levels for an engine .
Filtration is somewhat about trade offs . The finer you go , unless you increase the dirt holding capacity ( more filter media area ) the shorter the element life ... to a point . The initial start up is when the system is the dirtiest and when the filter life is the shortest . As the system is run and cleaned up , the element life increases ... until some component starts to fail or contaminant is introduced from outside the engine . As a filter "clogs up" , you do filter smaller particles out , but you also increase pressure drop across the element ... that and also cold start ups , is why there are bypass valves on the filters .
As a side note ... we used to make a lot of roller bearing pumps/motors for the mining industry since filtration/maintenance there was horrible . Testing and practical experience showed that the rollers actually crushed the larger particles into "smaller" ones and the pumps lived longer .... which a plain bearing can`t do .
This is a VERY basic and brief background on a very complex subject that filter companies have spent a lot of time , money and research on over the years .
Thanks for all your work on this subject that a lot of us will .... or should , benefit from !!!
