Code P2020 after Rebuild

[Pentalab]

So your saying that fully synthetic will pass through it Pentalab?

No. What I'm saying is.... when using plane 'Dino oil or semi-synthetic, (semi-synthetic is typ 3% synthetic and 97% dino oil, when tested) what collects in the catch can is what most of us refer to as...'the chocolate milk shake'. It's a combo of engine oil, un-burnt gasoline, and condensation.

Without the catch can, and when using dino oil, or semi synthetic, what happens is...all that 'chocolate milkshake' glop ends up all over the intake manifold, creating one helluva mess. It also lowers the octane rating of the gasoline used....since you are burning this cap in the engine. Folks who have taken the eng apart have taken loads of pix, and that crap is slopped over everything.

And for us folks who have a positive displacement supercharger, it gets worse. All that glop ends up on the intake elbow, and also on all the vanes of the supercharger impellor blades, supercharge casing, and then also all over the Intercooler. The typ intercooler is just a small radiator, and the glop will be all over it, through it, coating all of it. Then the glop ends up all over the aluminum intake manifold...then it gets sucked into the engine.

I have a 2010 GT auto, with the small Roush M90 PD blower. When I finally installed the catch can (and still using Ford... 'semi-synthetic' eng oil), the catch can would fill almost to the top in just 6 months. I then switched to RP 100% full synthetic. After the switch, the catch can barely has anything in it.... maybe 1/4" (6.35mm) of what appears to be clean, pure engine oil.

Other's reported the exact same thing, using various brands of 100% full synthetic eng oil.

I forget the various theories behind why this happens when 100% synthetic oil is used. The problem with 'semi synthetic' is..... none of the various brand's will ever state exactly how much is synthetic....and how much is dino oil. Several of the folks on another group had the semi synthetic analyzed in the chem lab, and were not impressed with the results. It's typ just 1-5% synthetic.

.. the problem is - to find 100% synthetic oil. Most of the "synthetic oils " are blended, with synthetic oil. Perhaps -but I am not 100% sure. AMSOIL is full synthetic... maybe some MOBIL OILs
..or MOTUL ( some of them )... But I know for sure.. 100% synthetic oil is rare...

I use Castrol Magnatec 5W-30 full synthetic and change it religiously every 5000 miles. The D5 specification for Ford vehicles is easily available in Cyprus.
During that period the oil level on the dipstick hardly moves, and my driver's side catch can collects ~40cc of darkened oil. Even after 5000 miles my engine oil still looks very good but I refuse the temptation to extend the change interval.

Thank you Dino Dino Bambino for the good oil advise . Currently I use Shell Helix Ultra 5w30 A3/B4 oil... But I will search the Castrol Magnatec 5w30 ... for the next oil change

Yes forgot about Castrol. Another oil I used fifteen years ago haven't seen on the auto parts store for yonks either.

Thanks Pentalab, So forgive me if I haven't understood you properly. Is semi synthetic is a dirtier oil and collects sludge in the catch can and fully synthetic doesn't? or does the the sludge not find its way to the catch can with fully synthetic?

 

[Midlife Crises]

Dino oil and semi synthetic oils foam and vaporize and get carried out of the engine through the crankcase ventilation system.
Synthetic oils are made to resist foaming and vaporize at higher temperatures than normally encountered inside the crankcase so there is less “oil mist” floating around inside the engine to be carried away. It just that simple.
Put 6 quarts of Mobile 1 synthetic 10W-30 oil in and 5,000 miles later drain 6 quarts out. Minus that little bit stuck in the filter.
What Pentalab said about oil fouling the supercharger and intercooler is absolutely true. I have seen it in my own engine.

Catch can goes on the drivers side on a 4.6L
And if u use 100% synthetic, it will not collect very much... 1/4". Use semi synthetic, and it will fill to the top.

lol this is accurate ..
i put my catch can on about `1,200 miles ago,, and yesterday i checked it and it had like 6 drops in it ...

i was expecting it to be like at least 1\4 full

 

[whitmanink]

am i the only guy using super tech oil?
project farm on YT did a great review on it..
why pay more for the same thing?
i also change ,my oil every 2800 - 3000 miles..

i wont use a supertech filter tho because they are alot smaller than the ford one..
and in this case ,,bigger is better .

A lot of guys dont go into big brand name oils, just over the counter cheap and cheerful and it does the trick. I dont like paying over £40 for a gallon of oil myself especially when you change it every 5000 miles or possibly sooner.

My oil choice at the minute

 

[Kev555]

Catch can fitted this evening, Let me know if you guys spot anything ive done wrong as I'm a catch can virgin. Should they be void inside with no filter? I got a piece of black sponge in the package but I'm not sure if its to go inside the catch can or mounting packing on the outside

 

[Pentalab]

Mine had what appeared to be stainless steel wool inside. Issue with foam is, it can melt, and / or disintegrate into tiny pieces. Did urs come with any detailed instructions ?

No, probably fell off a slow boat from China. no brand on it either but it looks nice.

nice oil you have over there in Ireland. A5/B5 A1 /B1. SL/CF... and all the Ford Approvals
Real nice stuff...

 

[Kev555]

Its about £30 a gallon so its a really good price too.

 

[brasil]

30 Bucks a gallon.. for fully synthetic oil is a real good price !

This is what I have inside my catch cans as a filter media:

 

[Kev555]

Thanks Dino, looks tight wound stuff so less chance of fragments being sucked in. Interestingly I thought the canister would be slightly pressurised coming out of the engine but the air intake creates a hell of a suction on it, I couldn't pull the lid off it hardly, when I did raise it a mm the car started to die. Id Guessed I was messing with the vacuum in the engine. judging by the vacuum I doubt any fine mist will be sucked though the catch can back into the engine without some sort of media in there?

I think thats about $40 going by todays exchange rate.

Quick question, what material is the outer door skin and wings on an S197 made from? I have a reaction on the two doors started one year after respray and looks really bad this year. I also see signs of it starting on the wings also. Bootlid as well. Ohh and my p2020 code is back again
