WHILE TOWING MY CARAVAN SOMETINMES THE OIL

NOT A USA CAR "GO SPORT ENTERVAN"?
GO?
SPORT IS A TRIM LEVEL ONLY
ENTERVAN IS WHAT.? WIKI SHOWS NO SUCH THING, WWW.
WELL 1 HIT
introduced its first wheelchair accessible minivan, based on the Dodge Caravan and called the Entervan. In 1999
SO IS A CARAVAN, HARD TO LEARN THIS, 1 HIT WWW.
GENERATION 4, 3.3L V6 EGA, THE Predsessor to my jeep wrangler 3.8L know so well.

I WILL NOW ANSWER FOR USA CARAVAN.
100%NORMAL (Pressures) TOPIC EVAP ! SYSTEM.
but only normal in the normal range.!
if it goes to a vacuum as all do on hot day and overnight the fuel cools and shrinks in volume (physics) and the GAS CAP vacuum breaker prevent tanks from self crushing, buy real OEM GAS CAP fixed
the pressure
as gas warms up in the hot sun it expands and pressure builds(physics) and pressure check valve at about 1PSI opens and sends vent fumes to the CANISTER box.
i will now show this check valve EVAP part to you , photo below.
SCAN THE CAR YET IF EVAP PRESSURE SENSOR WHY TO HIGH ERRORS? HUMMMMMMMMMMMM
some of the parts(all) can not be installed backwards vents hoses
or that wrecks the check valve insides a one way valve.
if you do that pressures go way way too high. not like below
but bulges.
bad vapor vent valve or purge valve or installed backwards
so bad cap
bad 2 valve vent,or hosed up backwards.
that is about it.
the fumes car parked in hot sun fumes go to the Canister,
ive valve that must not be clogged or put in backwards,.
and pressure is 1psi max./

cave in seen by me, cap is 100% wrong cap,

Check your oil level.

Wear in your engine could cause this, a worn oil pump, leaking seal, worn main bearings or camshaft bearings.

A weak oil pressure sending unit can also be an issue.

As the clearance in your engine increases with wear, the oil pressure will gradually decrease after a certain amount of wear.

You can increase your idle a bit.

You can also change the weight of your oil up from 5w30 to 10w30 or something similar and that will increase the pressure a minimal amount.

Depends also on the kind of tyre.
For the maximum load of tyre nex kinds need next pressure , wich is called AT-pressure/maxloadpressure/reference-pressure , for up to maximum speed of tyre or if lower 160km/99m/h. This is not the maximum pressure of tyre.

Normal car tyre /standardload AT 2.5bar/36psi ( exeptions as low as 2.2)
XL/Reinforced/Extraload AT 2.9bar/42psi ( exeptions 2.8 and 3.0)
6PR( plyrating) /C-load AT 3.8bar/55psi EUR ( USA 50psi/3.4bar)
8PR/D-load AT 4.5/4.8 bar/ 65/69/70 psi
From E -load is not often used in Europe.

From this AT pressure you can calculate the needed pressure for lower loads . Made spreadsheet for it in wich I first add 10% to the assumed load before calculating.
Will give example picture

The transmission was over heating. Have a pressure test done on the transmission as it may have been just good enough for normal driving but not for towing. Did you have the over ride brake on the van released and were the electric brakes releasing. You can fit an external oil cooler to help with the problem as most autos suffer over heat problems when towing.

Your oil pressure will increase and decrease with the speed of the engine. As long as your oil pressure increases, that's ok. The idle problem could be caused by a dirty fuel or air filter. I would start with replacing the fuel filter and check the condition of the air filter.

Heavier oil will increase the oil pressure. keep your eye on the gauge for the next few days & take notice of any change. If so have it checked out. Hopefully it will stay where its at for now. At 1200 miles the pressure should decrease some after the oil impurities are broke down

check the module and coil pack in the distributor

could be a worn oil pump or pump pressure relieve valve try finding a product called lucas oil stabiliers and use a full bottle with your next oil change should help bring the pressure back up and it will help you engine plenty

I had the same problem with My jeep, when i took it in to a shop, they couldn't find any problems, , after about 5 shops and a ton of headaches from the low oil pressure warning, they found out that the gauge had gone bad, you may want to look into it as well.

Turns out it was the water pump. The plastic impeller on the inside had broken in half- split almost right down the middle. there was just enough of the impeller remaining to attach to the shaft and pump water. Apparently, it was pumping enough to keep the temp under control. So, I never noticed it overheating. The piece that had broken off had gotten lodged in a recessed area inside the pump housing. The ticking noise was being generated as the intact half of the impeller rotated and hit the broken off half.

I narrowed down the problem by removing the belt and cranking the engine temporarily. With the belt off and the pump not turning, the sound was gone. I could spin the pump pulley by hand and faintly hear the noise.

A new pump cost me $35 and took about two and a half hours to replace.
