Is the PCV system on Pinto and Kent engines from mk4 cortina an open type pcv system?

[Dinoplex 1]

According to the desciption of wikipedia about "closed" and "open" pcv systems, it sounds like both pinto and kent engines use open style pcv system where it breathes air through the oil filler cap and not from a section in the air filter housing like closed pcv systems do. The haynes manual also calls it "semi enclosed pcv system" however the german tc2 taunus workshop manual calls both pinto and kent engines as "closed pcv system" when translating to english. Did the workshop manual perhaps make a mistake there? 

Wikipedia also says that open pcv systems under full throttle conditions still let crankcase vapors escape from the oil filler cap area and my pinto engine is a bit damp under the oil filler cap. So is that normal that pinto engines are kind of damped under the oil filler cap due to the open pcv system allowing crankcase vapors to escape from there under full throttle? Or maybe my oil seperator is too dirty and it cant properly seperate the oil from air properly so my oil filter area gets damp?

Thanks in advance

Yep they use the same system ( not sure on description) but it sucks air in through the cap & fumes are expelled into the inlet manifold & reburnt.

Any thing coming out of filler cap is from excess crankcase pressure either from worn piston rings allowing compression past into the sump which comes up the oil drains from the cylinder head to block & pushes oil fumes back out of the oil cap.

Or can also be caused by a blocked oil pipe & or pcv valve.

The cannister doesn't really get block . You can clean these with solvent( petrol,thinners,carb/brake cleaner etc).

Wetness near the oil filter is probably from a loose filter or failing filter seal, or leaking rocker cover gasket.

Pics would help.

The wiki and couple other websites talking about pcv systems were saying that the closed system was developed to prevent any gases escaping from oil breather to atmosphere to reduce emissions further, they say it can happen under full throttle where there is plenty blowby that it will exhaust from the oil breather also (even on new engines). But its very minimal , majority still goes to the intake so i guess its not enough to damp the area under the oil cap with oil stains on a perfectly fine functioning pinto. I will take and post the pictures from my engine here tomorrow. The front main is also leaking and cambelt throws that around so im not sure if its from that or oil exhausting from the filler cap.

This diagram from opel kadett ohv engine actually shows the arrows exiting out from the breather inlet in the air filter area of its closed style pcv system. I took this picture from its workshop manual and it said during idle and part throttle the fresh air comes from the breather but on full throttle with a lot more blowby compared to part throttle, some of the crankcase vapors will exit from the breather area and the picture shows both operations at the same time thats why the arrows are a bit messy.

The kadett one works differently to the pinto one in the way it routes the gases, I'll see if I can find a diagram but I'm not very good with computers.

Yeah the kadetts is closed pcv i think , like the köln v4/v6 engines. I have these diagrams for pinto and kent from the workshop manual. The kent one is great but the pinto one doesnt show too much. Interestingly enough the german manuals call both pinto and kent as closed systems like the köln engines but in the diagrams they show the köln engines pcv system is of the closed type like the kadett ohv engine and not like the pinto/kent, im guessing maybe the manual did a small mistake with naming.



By the way, i took pics of my engine bay. The front main is leaking so its throwing some oil around via the cambelt so there is also that. The valve cover gasket was changed about 8 months ago btw. The oil filler cap sits tightly and there isnt much blowby  from there, the compression on the engine was also checked 8 months ago and it was healthy on compression.

The cologne eng works the same as the other fords of that time, that's very good for a pinto of any age/condition, the staining around the filter is again pretty normal probably what's dripped from the rocker cover.

I be pleased with an engine that clean & leak free.

Oh i see, i thought mine was kinda on the leaky side. Thankfully our MOT in turkey barely cares about leaks like that so it just passes them no problem. Apperantly theres this thing called "SKF Speedi Sleeve" that can seal worn shafts and my front main seal was changed and was still leaking so i think my crankshaft is kinda worn out at the front and not sealing with the seal properly. But we dont have that product for sale in turkey and i cant buy from european sites because our gov is........................ , so im basically stuck with that leaking front main seal.

Hmm , what about places like Australia/new Zealand or china?

Or can you get two part epoxy type things like araldite or chemical metal. There's quite a few of these type things used by model makers too.

Plenty of things here  under £10 sterling ( no idea on shipping price but it's very small) but would they allow something from a non business/private source .

I said europe but its actually basically everywhere. I live in an absolute sh*thole joke of a country, they reduced the maximum price of abroad shopping to 20 dollars including shipping and not only that the seller that you bought that part from has to have some "official authorized individual" within turkey to "provide support" in case a i have a problem with the product. An insane law basically, surely some ebay seller in europe will hire some guy in turkey to do those things just so i can buy stuff from him XD. If you buy something that doesnt satisfy those conditions  the customs just confiscate whatever you bought. The reason they brought those laws is because everybody was buying stuff from temu for waaaay cheaper than the massive turkish online sellers with their massive markups and those sellers are close with government so to protect them the clown gov brought those insane customs laws. And after all that if you manage to find something that satisfies those crazy conditions, you pay 50% customs tax if its shipped from eu and 100% customs tax if its shipped from outside of eu XDDDD

Thanks for the advice with the materials like araldite, i didnt knew about those. I will check if we have those sort of stuff available in this sh*thole

Ah, now here in the UK if you sell online in one year more than 30 items or a total of more than£1500 you've got to pay tax the same rate as your wages.

So if you sell 30 things at £1 each the 31 is classed as earnings.

 

I'm sure post COVID the world has gone mad.

 

Good luck & if I can help with anything else get in touch.

Ah damn that also sounds pretty bad, indeed as you have said the whole world went mad post covid 
Also thanks for the help

Your engine looks damn clean !  

 

My 2.0 pinto has a bit more dampness I think from the filler cap, it's had a big head skim and has healthy compression, also sees a bit of full throttle action !    I'm not worried .
