Did anyone else having this failed hose have a problem with the idle being too high or get a lean code? It took me a while before I realized what was causing all of that.

This job is a serious PITA. I wish I'd have done what warneej did--I sure don't feel good about the new Ford piece I put back on there.

There's no telling what all got sucked up by that damned crack. My intake manifold was all gunked up. The tumble flaps were pretty caked too. It took a while to clean it all up. Hope there's no long term damage.

I highly recommend putting something sticky/gooey on your socket--a dab of grease should do it--when reinstalling bolts. I dropped one and it took a while to figure out which bottomless pit the thing disappeared down!

I hope the next time I have to do this, I'll remember what I did before. ;)

The pcv hose isn't the worst when it comes to quality, it's not gold but it's also just a hose. There are a vast majority that have them last quite awhile and then of course polar opposites. If it lasts 100k then hell I'm pleased (but I do have lower standards) I already have a new one sitting around.

I still think its wierd but my car ran great, no codes, no wierd idle, same great mileage, same performance, etc...

You sound like the wife whose husband always beats her, but its ok because "he loves me".

The hose is a poorely engineered piece of shit. Just admit it. I have 20 year old hoses on my bronco that still work, including the PCV hose which BTW I could replace in about 10 minutes and that includes the time to open my first beer, finish it while working and go for a second.

True, but it's not an overwhelmingly occurring problem, not everyone encounters it, and plenty of different cars suffer from this part. I'm surprised there aren't more actual valves getting clogged/broken and people just having to replace the hose. My only reason for getting a new one is already having the engine out. Well that and I broke the hose getting it out.


Don't get me started though on the pain that is FWD. I'd much rather argue about the engineering on that than a hose.

Amen! I don't know how many times I've looked at the manual for an R&R procedure and said, "You gotta pull WHAT?!

Yeah i had the same issue with the hose fitting, it seems as though every piece of hardware that came with the manifold was either the wrong thread pattern or too long. My first fix was with a longer hose but that ripped as well.

I didn't get a code or anything and the symptoms were different both times. The first time my engine started running like I had a massive vacuum leak, although I couldn't find one. Symptoms included idling like I had a massive cam, terrible gas mileage, lean spikes, etc. The second time the car ran just fine however it just made that super loud whining noise.

When I pulled off my stock manifold (the PCV hose was still working fine mind you) mine too was caked with goo. I think its what comes through the EGR that causes that. I deleted that in my tune.

Definitely awesome thread dude! I always wondered what the procedure was like and what it looked like removed.. So it doesn't seem like the installation of a Cosworth IM is THAT bad.. Although warneej might think otherwise on the matter lol

The intake manifold install was the easy part

Assuming the cosworth is well engineered the install should take like 6 hours tops.
