    Oil System chacteristics after Jdub's Oil System Upgrade

    Did you replace the oil squirter bolts? Since it's not shimmed, your pressures are ok, but a bit low for a full flow system. Make sure the return from the cooler is plumbed to the center fitting on the block adapter (the NA stud is the feed to the cylinders). Mixing the fittings up on the...

    Oil System chacteristics after Jdub's Oil System Upgrade

    Kenny - is your oil pump relief valve shimmed? Getting precise readings from the stock gauge is problematic - check at the stock gauge sensor location with a mechanical gauge. Check and make sure all hoses are routed correctly - I assume you are using a NA stud with the PermaCool adapter?

    Oil cooler sizing?

    That should work nicely for most applications ;) For extended track use, you may have to dedicate both coolers (hooked up in parallel) to the oil. If you have them stacked in the airflow, the oil cooler should be in the front. To check for a specific oil fill quantity, fill till the oil is at...

    Oil cooler sizing?

    The larger cooler are space prohibitive (installing wise) as well. Setrab is a good cooler - take a look at B&M. The size you posted should work.

    Royal Purple Oil - Turbo Killer?

    This is interesting since RP uses the most common synthetic base stock (PAO) you see in the high quality oils...the same base stock German Castrol utilizes. The difference is in the add pack. Think about this for a minute - if RP contained additives that would cause a turbo to fail, would it...

    Cooling system Stop Leak products?

    You are correct - wrong section - moved to General. Concerning the coolant system stop-leak products - use them if you really want to trash all your coolant passages. Including the block. How about forgetting a quick fix that will just induce other problems and fix or replace the heater core.

    Oil cooler sizing?

    As big as you can fit - the T-stat will handle flow through the cooler for proper temps. I prefer the stacked plate design...more efficient for the size, better flow, and less susceptible to FOD.

    bypassing the EGR

    7mturbo - I highly suggest you ignore this post. Supraflymk3 - Get your facts straight before you post in the Tech Sections again.

    bypassing the EGR

    Sure it's possible...is it smart to do so running a USDM ECU, well, that's a different story ;)

    excessive blow by, compression and leakdown results inside

    Not sure what "ATF trick" you are referring to, but running ATF through the intake (like the old school Chevy guys did) will not work.

    excessive blow by, compression and leakdown results inside

    #6 could easily be due to a HG - coolant in the cylinder will steam clean it. If you put Seafoam in the oil, all you will accomplish is to reduce it's viscosity. Don't do it. The Mopar cleaner is good, but I have always used it to clean piston tops with the head removed. You could try to...

    High oil pressure?

    Sometimes I wonder why I even post.

    is it necessary to run a thermostat in-line with an oil cooler setup?

    I've used Summit twist-tight hose/fittings and never had a problem with it...I did use the 3 barb AN type fitting vs the 2 barb NPT. The Aeroquip fitting you linked to looks like a std brass barb...it's not push-lock...there is a difference. Aeroquip makes good stuff - you won't go wrong...

    High oil pressure?

    19-20 psi at idle is too low???? WTF over. Chris - if you are using the stock filter head to pressurize the cooler circuit, there is no way it (or the line to/from) can be responsible for a 20 psi idle pressure - the cooler relief valve doesn't open till ~40 psi. A blocked filter won't do it...

    Idling problems after startup when engine has warmed up.

    Excuse me? Care to explain exactly how he can "increase your idle to about 750-800"? Step #1 - Check for ECU codes.

    redma70's full motor swap

    Brand new MHG - never been run. Tell me, what are the odds the viton will separate from the metal layers? I have a novel idea - take the head off and take a look. The cylinders must be honed anyway and it just might be a good idea to assemble the engine in the correct sequence with the correct...

    is it necessary to run a thermostat in-line with an oil cooler setup?

    You do not need clamps with push lock hose/fittings. Waste of time and $$$.

    Poor motor oil selection and excessive temperatures in rebuilt 7m

    Cooling system: - The stock ECU looks for coolant temps between 76 and 100 deg C for normal ops. Below that range you are in warm-up enrichment - above the ECU pulls timing. - Your radiator should have the thermal capacity you need. I suspect the fan (lower temp to 85 deg) or you do not have...
