oil

1990 Ls400 180k miles. Recently changed my oil and started having oil pressure issues. Once the car is warm, the low oil/ low oil pressure light comes on. Before it had only came on if I was a little past the oil change and was low, but only if I was going fast. This time it came on right...

This may have been covered before but it doesn't hurt to post it again. Engine hasn't been started for almost 2 years now. Haltech and fuel system all sorted Just needed to confirm oil was flowing from the turbo oil feed pipe before enabling injectors. Cranked about 5 times for 10 seconds and...

Been investigating the engine oil and its pressure Vs temps. Until today, I have the standard small oil filter (Ryco Z418) and 10w30 oil. The main issue was the idling pressure that would sit around 16PSI when the water temp was 90+Cdeg. When cruising at around 2600rpm, pressure was 67psi...

Hi all, I want to wire the oil pressure gauge on my 1uz. I've got the stock pressure sender, but a VDO oil pressure gauge I'd like to use (or I will use any other if there is a known one that will work accurately). How do I work out what gauge to get? Do they have a standard for volts vs psi...

Just finished up turboing my sc400, oil temps are 240 after a spirited drive. So I ordered all my stuff to plumb a 25row setrab oil cooler. I want to keep it on the driver side however my p/s cooler and bov are limiting my space on the driver side of the bumper. I was tossing around the idea of...

Hi All Anybody know how much oil the 1UZFE pump flows at 2000 rpm ?? Many Thanks Alan

Hey guys so i have pull the front end of the truck apart to change fan belt and some general tidy ups as its been sitting under a tree for the last few months and noticed that the oil cooler was setup in a way i wasnt familiar with. opened the connections and it was still brand new inside...

Anyone know if there is any place I can get oil from, not a lot, just for a bypass oil filter. Typically oil pressure sender is chosen, but wondered if there is any other place. Many of the GM engines in trucks or HD applications (LT1's) have factory oil cooler lines fittings built into the...

So Here it is- I want to boost my car. It is a 99 GS400 with VVTi &E-shift. I have am immediate budget of about $1800 and a complete budget of about 4-5k$ I will like to have extra power as soon as possible. I am willing to try supercharging fro now due to $ and then later move to...

Hey guys need some help, have 1uz in early 90s hilux (had 22r) and now 1uz anyway sorting on the oil pressure gauge (using stock gauge) so I put the 22r sender on the 1uz as the original 1uz sender was just a switch I presume? As didn't have any resistance. The gauge works but reads dead...

Hey guys, with the standard oil pressure switch, does the ECU need to see the oil switch? The reason why is that I have replaced it with a Mercruiser unit to suit the gauges in my boat. Will I need to put the standard one in line somewhere in the oil system for the engine to work?

Hey all, The oil pressure weve been seeing is 50psi at idle cold, 25psi warm. Under revs this increases to 50. I figured this is ok, other 1UZ's ive seen are the same. Yesterday though I ran the oil breather lines out ofthe rocker covers to an oil catch can and under revs its now pushing...

I was assembling the built V8 tonight and I was thinking if it's possible to optimize the cooling system a little. Looking at the engine it seems the front is better cooled than the rear (like most engines) so that can be improved. How about anything else? Are there any hotspots in the heads or...

Guys, Can anyone tell me the thread sizes on the Oil pressure switch that screws into the block as I'm looking for an adapter that will screw into the block that will accept both the original oil pressure switch and a new sender for an oil pressure gauge that uses a 1/8 x27 NPT thread. The...

Hi there, I'm new to the forum as have just got hold of a UZ to put in a project vehicle, first task is the dry sump design, many thanks to all the contributors the forum, plenty has been learnt reading so far!!. has anybody the flow-rate figures for the oil pump on a 1st gen UZ???, im...

What do u guys think of this setup for remote and low mount. Assume the reservior tank is 4" x 12". That should hold about 4-5 quarts along with oil cooler and other lines add up about 6-7 quarts. Would this system allow enough cooling?

A Honda tuning company named Whitfield Racing here in CA has a high NA power B20 VTEC engine. The car was only making avg. power until they found a way to relieve oil pressure some how and the monster motor put out something like 50-75 more HP. Anyone ever heard of this type of issue when...

hey all, we went to fire the racecar for the first time on the weekend, and aside from a few wiring issues we couldnt actually start the engine as winding it over we had zero oil pressure. I'll be pulling the engine out tonight and pullng the sump to make sure that Ive not done anything...

Dear All, I am looking for an oil cooler adaptor kit. this adaptor should be installed between the oil filter base on the block and the removable oil filter. The kit got 2 outlets for the oil hoses that will lead the oil to and from the oil cooler. Any idea where to get one? Thanks Guy.

Just want to know what normal oil pressure should be? Im running an aftermarket autometer oil guage and sender in the original oil senders spot. Engine is 1UZFE from crown at idle I get 55psi and at rpm I get just short of 100psi.
