1GGTE Oil Pressure

[Gttwinturbomk3]

Is the pressure up to about 80-90psi on cold start up??

its probly the hydrolic lifters filling up with oil thats why the noise will go away after 3 seconds... leave the car unstarted for a couple months i bet the noise will continue for a minute or too

Hi,

But the thing is I only get the noise on the first 3 seconds of startup when its cold, otherwise no noises while driving. The oil pressure light never comes on when driving cold or hot.

Motor has done 67,000km.

if it is only for the first 3 seconds then id say its just lifters priming, my '03' navara does the same thing on cold days and its only got 60,000 on the odometer

Oh ok.

Think was my other Soarer would never do that.

im really hopeing thats whats wrong with mine, but its a fucking nasty sound, it would have to be the worst lifter noise i have ever heard.

1G's don't have hydraulic lifters...

Yeah just bucket/shim.

My oil level is good too right up at the top mark.

double post.

My 1g runs the same pressures as yours. I've been a little wary of the noises it makes, but i always am with any engine. Mine makes the knocking noise for a while when warming up, apparently it is fitted with CP pistons. I took it to Silverwater Auto as i was concerned about the noise level from the top end but they told me it was normal. I also watched a video on youtube and that engine sounded the same. Guess they are just a little noisy!

my engine makes every noise you can think of, i still ride it hhhigh into the revs and havent had a problem, and thats around a years worth so far i always get a consitant 55-58psi while crusing and 20-30psi on idle

[kerzysgotasupra]

my oil pressures about the same as those shown here for a 1G-GTE though i use 10w30 semi syn not 15w40. i was told that the oil gallerys on a 1G just aren't big enough to use an oil much thicker than this, it may also explain the relatively low oil pressures compared to some other engines.
also as mentioned in previous posts mine "knocks" and seems to be from the cylinder head area. its always done it, can't find out for sure what causes it, still pulls like a train upto 6600rpm on 1.3bar boost, so i'm gonna leave well alone

I would be a bit wary of your engine builder if he is talking about the noise being a nasty lifter noise, as has been mentioned they run shims ( which he should be well aware of !! ) so the noise is not going to change with or without oil pressure, my 1JZ has a slight knock on start up & i'm sure it is bearing noise as the noise goes away as soon as the oil pressure light goes out, if it was piston slap as has been mentioned it will be there for at least a minute or more until the piston starts to expand as the temp increases & you usually will not hear piston slap at idle ...

I have been thinking about fitting up a oil pressure supply tank, it feeds the oil galleries with oil under pressure on start up.. It can also be used / helpfull to stop oil surge starvation on hard cornering too, i think Morroso do one ..

[scottreichstein]

is it worth shimming the oil pump if so how easy is it and could someone explain how to cheers

[Kedderz]

if your building a motor, do a search on the forums for 6boost oil modifications. They explain the mods kyle did to his 9 sec 1g.

[scottreichstein]

cheers will do im not aimin for 9 sec hilux thou ha ha maby when the 1g blows and then put a 1jz in it
