I've got some seepage coming from my crossover pipe to intake manifold gasket, and IM to head gaskets. I'd like to pull it all apart and clean it out, do these gaskets need to be replaced, or can the be cleaned and re-used?
 
Seepage? The only thing in there should be air. If you've got oil seeping from there it's coming from blowby or turbo seals. Removing the stink hose from the air intake should help with some of the blowby. Either vent to atmosphere or an oil catch can.

Technically the gaskets are one time use, but I've had mine on and off a few times without issue.
 
I've added a catch can and it's made a big improvement, but the oil that got all through there is still in there and I'd like to pull it all apart and clean it out. Probably best to just replace them all then.
 
I would recommend genuine gaskets and also replacing the seal washers.

As mentioned you need to take off injection pipes so worth getting new gaskets.

The minor oil in the crankcase vent is enough to seep and stain the head when there us a very minor leak even if it is half a teaspoon over 5000km.

Oh you've got to actually remove the injector hardlines to get the IM out of there? I should really just go have a good look at things and I'd know that. Well that IS a PITA compared to what I thought I was in for...
 
If Mr. T said 1L ( quarter ) of oil every 5K it's ok .. there must be some oil going into the intake that's mostly normal ..

If it was staying in the intake tract that would be one thing, but it's seeping out the gaskets, and was dripping from the turbo before I added the catch can. The issue is more or less dealt with via the catch can, but the mess remains, and I'd like to know it's not also losing boost at any of these points, hence the gasket replacement.
 
I found better economy and small improvement in AFR after replacing gaskets.

Yes you need to remove the injection pipes. PITA.

Yup. It's the injector lines and tight spaces around the manifold runners that make it a PITA , unless you have little hands and long fingers

I had this problem with mine. I pulled all the intake tract out and gave it all la good clean in gasoline to get rid of all the oil residue. Once cleaned up I found the rubber intake hoses sealed up much better without slippery oil all over them.
 
Can someone throw up part numbers for the gaskets and the seal washers?

Crossover pipe to IM gasket: 17115-17010
IM to head gaskets: 1X 17171-17010 and 5X 17179-17010

These seal washers, they are between the fuel hardlines and the injectors, correct? Any chance you've got a part #? I can't find a diagram with anything shown there.

Edit: well that didn't show up for some reason...

Can anyone clarify where the seal washers can be located?
 
I get 90201-08106 at ToyDYI in the injection nozzle detail. EPC shows a host of applications. Two per nozzle. You want slide 22-01 in either EPC or DYI.

EDIT: Crab's got it...see pic above.
 
@Crab Sack I'm a bit confused, the copper washers are what I thought @David60series was referring to, but your pic shows a rubber seal for the bolts holding the IM to the head being called "seal washers"?

Copper washers, 2 per injector, so I'd need a dozen of these, correct? Have you had your manifold off already, and were the seal washers 90210-08041 needed/deteriorated, or you just got them incase?

You need 12 of the copper washers.

Correct, you need 12 of the copper washers for the fuel rails.
The seal washers are for the intake manifold and mine were a bit dry but otherwise in good shape. I just got my manifold off last night to pull the injector pump to rebuild. I don't like to re-use gaskets so I opted to replace all of them while it was apart.
 
I see where you were going now. Thought you did not see the details in EPC or DYI.

Sounds like you have a job in front of you. I probably should at some point as well, having run with blowby hose hooked up for a while. Now I'm to atmosphere, but there is some oil staining along there from before.
