Having 3 issues with car
Subscribe
Hi guys, my 650hp project has been going quite smoothly up until now. I discovered 3 issues with the car this week.
1) I found some creamy white stuff around the oil filler cap. Not a lot but little bits all around the cap. This scared me and I am getting worried about a head gasket failure! I do not do short journeys and car is always warmed up and cooled down. Also, car has been losing oil lately.
2) After the GT2 Slave conversion, I have a continous pentosin leak from the pump
any idea why that could be. The pump never ever ever leaked before. I removed it and reseated all gaskets and seals and tightened the screws up thoroughly once again upon discovering the leak.
3) The valve on the coolant header tank is stuck open. Is there any danger to the car like this? Temperatures have been same as always, Needle stays on 80 degrees and maybe only goes a needle width past 80 when in traffic or spirited driving then slowing down.
This is a picture of the valve im referring to. ALL HELP IS MUCH APPRECIATED!!

Creamy white stuff is what happens when water vapor and oil vapor combine. Common in that area because it is a cool area. If you are concerned about head gasket failure have the engine oil analyzed for any signs of among other things anti-freeze in the oil.
I have seen this creamy white stuff under my Turbo's oil cap (Boxster's too and it is just a characteristic of these cars. The engines take a while to heat up and even then don't always get hot enough to boil away the water in the oil. That you seem the creamy stuff is a sign of that. My recognition that this occurs is to adhere to a 5K mile oil/filter service interval to drain the oil from the engine before the moisture build up becomes a problem.
The oil consumption could just be normal. Both of my cars use about a quart per 5K miles. Hard running/high rpms in either car will up the oil consumption rate. IOWs, the oil level remains quite constant then I get a bit crazy. When I check the oil level the oil level has dropped maybe a bar. I then cool my jets and with more sedate driving the oil consumption slows.
I'm not familiar with the conversion you speak of, that is I've heard/read about it and know a bit about it but I'm not familiar with the things that can go wrong if it is not done right, or if one the GT2 parts is bad.
I know when my Turbo started leaking fluid from the fluid reservoir under the plastic panel under the frunk ahead of the driver it proved to be due to a bad slave cylinder.
If the valve is open on the coolant tank the cooling system can't maintain pressure when hot. This can lead to localized overheating in the engine as hot coolant flashes to steam at the hotter spots in the engine.The steam can block coolant flow and the areas get way too hot. The coolant temp gage may not register any scary rise in temp simply because the heat is not being transferred from the engine to the coolant that flows past the coolant temp sensor.
It is critical these engines have a properly functioning cooling system. You need to get the system pressure tight.
Sincerely,
Rockster.

Its normal for the pin to lift on the valve in your pic when the car is upto temp. when cold it should go back down.
When the pin lifts up the coolant system is still pressure tight, it does not indicate a leak.
As Macster said its normal to have some creamy gunk around the filler neck in the winter.
If you are concerned you have oil and water mixing you can remove one of the plugs on the oil canisters under the turbos and collect the oil.
Only a small amount will come out, less than 1/4 of a liter, you can then have a look at the oil to see if it is showing any signs of creaminess.
If all ok just pour the oil back in the filler pipe and remember to tighten the plug again.
