I was always told that the cam phasers do not enjoy anything but 5W-20, and that people switching to 5W-30, 10W-30, etc. were actually harming their truck. As finicky as the 3V's are about oil pressure, I personally would not want to go thicker.

 

I watched Makuloco's oil video on youtube and it's a confusing video as to what it's really about. He starts discussing the importance of using the right oil and how much oil has changed in recent years. He does this from a NASCAR race and engine shop and tries to make his point with NASCAR engines. Engines that have no relationship with someone's daily driver. He does mention NASCAR engines run at ~310 degrees but leaves out the coolant pressure for a NASCAR engine is around 100 to 110 psi, uses no thermostat, uses no coolant (Monster Energy Series), has auxiliary ice cooling, taped up radiators, drafting strategies to avoid overheating, strategies to control intake air temperature, that the block and fluids are preheated before starting and racing, etc., etc., etc. Importantly though, he doesn't mention the engines are rebuilt after every race and the engines are not rated in expected miles but in expected hours. Oiling and lubrication breakdown\failure is expected. Discussing the daily driver in terms of a NASCAR engine can be extremely misleading if anyone that watches the video gets the impression that the information are suggestions for their car\truck. What he does would be like an F1 suspension mechanic trying to explain the basics of the daily driver suspensions in terms of an F1 car. Anyone believing that it's a good idea to start at the F1 basics of matching the center of gravity with the roll center height to eliminate body roll in a daily driver would be a good way to kill yourself and others.

He does relay important principles about oil. No question. He just uses examples that don't apply to the information he's passing along.

 

I appreciate that. I am trying.

Nothing wrong with boxing the frame and a whole plethora of other upgrades. Doesn't matter how long it takes. The time it would take is going to come and go whether you do it or not. So do it. Have fun.

 

Yeah, they also run higher volume oil pumps as well, River.

I would like to see the context in what Makuloco was saying in the video JP mentioned.... does he recommend changing AFTER the M360 oil pump is installed? I can see that being OK. With the M340 though, I would not switch, personally.

 

I'd like to see the video also. I couldn't get a link to it from JP's screenshot. About a different pump? I don't know what I'd do. I can also envision the need to go to a lower viscosity with a higher volume pump. Particularly with hydraulic properties of oils now that you mentioned earlier. Raising volume and viscosity might overdrive something???? This is the kind of question that hopefully the paperwork that comes with a new pump would explain and answer.

EDIT: I'm reminded of about 30 years ago when I overstepped and installed a high volume water pump. The pump made the thermal issues worse because the coolant went through the radiator too fast. I got a proper *** chewing over that one.

 

My bad guys. I didnt think to link the video earlier but I will below. He says in passing "switch to 5w30 as soon as possible" while he has the hood open. I am running a high mileage semi synthetic 5w20 right now but if the 30 can help keep an engine with some miles on it running well then I'm all for it.

River, I'm actually sanding and fairing a 200 Yamaha cowl right now so I can have it in good shape before it goes on the boat. I have no lack of projects but I will get to the bronco at some point.

White, the 4.0 is supposed to be as close to plug and play as it gets so that will probably be the direction I go in. I really just want to find a 91 explorer to pull the engine, axles, and harness from and I'll be in good shape.

 

Nay to that 4.0. Wilcox has 600 HP, 2.0, BDT Cosworth's for 29,999 Eng. lbs now ($36,435 US). It's the backbone of the 2.3 but oh, just sooo much more! (There's a BDT to your left)

I know. I know. I just really enjoyed writing that.

 

I still don't get the link. Tried the developers tools to get the associated link but you tube says it doesn't exist.

 

I don't doubt Makuloco's abilities as a mechanic but he has changed hats with this advice. Other than forum talking heads and sources like Hot Rod Magazine journalists I can't find any what I would call IMO, reliable, credentialed sources recommending a change in oil. Maybe we, meaning you lol, should leave a comment to him asking for documented reasoning for the advice? His advice\suggestion could have real consequences and not good ones.

We've gravitated to older vehicles so we deal with a lot of the long term effects where those that buy new vehicles and change the recommended oil never have the vehicles long enough to experience the effects of their "wisdom."

 

Saw this today. It made me think of 2100. Its for sale. 3k w 360, 4spd etc. Missing two lengths of trim though.
