i have at least 3k in fixing these issuse with this kit i could have had a badass single setup for the amount of cash i have in my aps kit but i dont give up on things so for now im riding it out it should badass after all of this the LG turbos still have not show up yet but some time this week i hope

 

Was going to ask you how things were coming Tom buddy! So still waiting for the snails.

I just got back from brief uneventful drive in the 99 a few minutes ago.Started raining pretty hard so not much fun today to be had. Nittos are better than pure drag tires in the rain but mine are pretty worn down. No traction control can make it more fun still.
Temp was running like 176 today but didn't turn on the air. It was cooler today too maybe 75. I am thinking part of yesterdays overheat was do to mabye my playing with my tuning .Since the reflash to previous settings seems to be running a lot cooler.
Still will be getting a bigger rad/better water pump over winter.
Can't be too rich or too cool!

I wish didn't have to buy my new auto trans this season but already have payment taken on my current t56 to local bud. Then could upgrade those snails sooner.
Be very anxious to see what numbers the new LG snails get.

I would call you Tom but our phone bills are nuts.give me your email again and we can do that maybe better than pms.We can fly out and visit each other for what it costs in phone charges.

 

I was getting terrible oil consumption but i believe this was due to the recommended APS PCV setup and not the turbos burning oil. I have always had some consumption but after changing it to have each valve cover vent to the APS inlets and swapping the check valve it was noticeably worse. After only 200 miles I pulled my intake after seeing my oil level drop and the thing was soaked in oil and my nice new heads were too.

After this I sealed up my valve covers, PCV fittings and added a vacuum pump and am pulling about 14" at 6500 rpm now. This was all done before I ever got into boost or had it tuned.

I saw/smelled zero smoke/oil when it was on the dyno and can’t see any when i punch it nor have I smelled anything unusal (except for my passengers crapping themselves when i punch it on high boost). The only comments people have made when driving behind me is it smells like a crazy lawnmower but no mention of smoke. I've got about 1k on the current oil and it looks amazingly clean. I have not needed to add a single drop since adding the vacuum pump. The pump seems to be getting enough oil vapor to keep lubricated. **Edit- the pump seems to pull about 1/2qt. per 3,000 miles**

I spoke with Lou @ LG a while back and low oil took one of his APS customers motors and I believe it was due to the PCV draining oil into the intake. Lou didn’t sound sure of that being the cause but who knows; I didn’t get a ton of details about the situation. Personally I didn’t and wouldn’t just run a breather as it is marginally, if any, better than just running it as recommended into your intake.

I'm still totally satisfied with my APS kit. Just wish Peter would respond to my PM attempt.

 

Hmm. I have seen no blowby to speak of really out the breather. But think still going thru oil. It could still be coming in thru the intercooler pipe from the turbos or be burning and going out the exhaust directly from the turbos.

So what did this vacuum pump and setup cost.Aren't they big money??
And how hard to install? Any pics of it..

 

Huh, that is not the problem i was having. Everything before the TB was clean for me... I'll snap a picture and post it up in a bit. The pump i got was GZ Motorsports but it requires you remove or move your AC condenser. It wasn’t cheap but there are a few guys selling used kits on here.

I'll eventually just run longer lines for the condensor and relocate it but at the moment I don’t have AC. Also, with the APS kit putting the radiator at a steeper angle it really is a tight fit between the pulley on the vacuum pump and the radiator overflow. Here is a pic from their website...

 

i was looking at that pump to its looks like a nice set up


hey Al whats up i call LGM today there was a issuse with the shiping but they took care of it anf there be here this friday send me copy of your tune ill send you mine and we can look them over

 

Holy moly that vacuum setup looks lke hardcore stuff! Too expensive and involved for me.
I maybe figure things differently.Turbo can only put oil into engine a few ways. It can send oil in via the intercooler pipes. It can't really put any in thru the exhaust. It can burn oil in the exhaust of course. Engine can put oil in thru the pcv. shot rings and blow bly can put oil back into the intake. Under boost it can make more blowby and more oil can get into the tb thru the line into it.

So scavenger pump should help if the turbo is leaking oil out into the intercooler pipes on discharge side and possibly if its leaking oil out the intake side and also if its leaking oil out its exhaust side. Assuming turbo bearing and not completely shot letting it just go by the seals.

Vaccum pump should help for blow by and blow by under boost but if you have that problem big time think that your engine is not in good shape.

I think am going to find my oil is coming thru the intercooler piping since don't seem to be seeing any blowby in my little test by blocking my intake and valve cover outlet.
And line to pcv looked dry.

Not great gravity feeding or mabye problem gets worse from hard acceleration or a bit higher oil level maybe from a bit of overfilling and you would get oil thru into intercooler pipe and out the exhaust and even into the inlets where guess it could be sucked back into the valve covers if its pulling air thru there as aps has it.

No you guys correct me if my thining is wrong here.

I have to inspect my turbos soon and see whats up. I am seeming to be going thru pretty good oiil running 10/40 now. So if its not leaking and engine is sound it must be coming from the turbos from it getting by the seals or from gravity not doing its job.

 

wow theres alot of issues here. so looks like im adding a scavenger pump to my list of items. you guys think i should initially run the system with the water cooling as well and see how it does?

 

Here are a couple shots of my setup....

you can see where i need to fix the kink in the line since the pulley is so close.

 

thats a clean setup im planning on goign the same route. what scavanger pump you using and are you running a methanol injection kit? i would appreciate more pictures

 

I think you're getting scavanger pump and vacuum pump mixed up... What i've got is a vacuum and it pulls air from the crankcase helping rings, seals and keeping oil clean among other things. Some of the other guys are talking about a scavanger pump to draw oil through the turbo. I am not running a scavanger pump.

 

Nice looking vacuum pump!
I have been doing my own experimenting. I had oil in my tb. I recently blocked off the intake port where the check valve goes and also blocked off the passenger valve cover that goes to the intake port. I just have a breather on my passenger valve cover.
I have seen zero oil spray on my hood with just the breather. I double checked today to see if am sucking any oil from the turbos into the intercooler and into the tb that way. Zip..nada. so it was coming thru the intake port obviously.
Now can put catch can on that line or my mechanic racer buddy figures simply leave that blocked. Put maybe a second push in breather on the passenger side . a small one in the current grommet. Delete the breather lines coming from the aps turbo inlets.
And thats that. No vacuum pump needed.
As for scavenger pump don't think actually seeing much oil coming out of my turbos at wot. I have none at idle and dont think any part throttle. I did have black smoke at wot but that is black from rich and was getting a lot of it as was misfiring badly but that problem is finally fixed.
I will install the scavenger pump sooner or later if start to see oil from the turbos. Upgrading to the better LG turbos anyway so maybe will be one of those 2/12 or whatever guys that Louis said don't need a scavenger pump.

Anyway my method of simply running maybe two breathers and not running any pcv at all is that really such a bad thing?

Seems like a real simple solution. Also can you put the passenger valve cover on the drivers side and then would get a place to put another larger matched to passenger side breather? Do the coils still bolt on..? Just wondering. Never tried the passenger on the drivers side.
But a smaller breather in current gromment might work fine too. I don't like the aps breather lines more clutter and crap on my engine.

 

take a look at this....

yep im retarded i know the difference didnt look at the plumbing lol. are you running methanol? and also do you have any high flow cats or completely without?
