I have read and reread the FAQs and am confused. I am clear on the fact that the turbo has no flame trap, but does have the associated hoses that need to be cleaned or replace.

I thought the simplest thing would be to just replace the hoses, figuring that after 8 years and 80K miles they were due. But my confusion comes from the location of the hoses to replace.

From the FAQs:

"The flame trap is located (buried is more truthful) under the intake manifold between headers 3 and 4"

That sounds like it would be hard to get to to replace the hoses. On the other hand, the IPD catalog says:

"Beginning with 1988 models, the filter was relocated above the intake manifold for easy access. Our kit includes everything you need to convert your Volvo to the new configuration, including detailed instructions. This turns a job that can take up to an hour on some models into a 5 minute service."

I have a 1995 and am hoping that it is only a 5 minute service. Does anyone have any pictures which show which hoses we are talking about and how easy or hard they are to reach? How about a description of the parts (Volvo part numbers would be really great)?

Thanks.

No pics, but I think I can describe pretty well what you're looking for.

Find the large foam-covered hose that runs across the valve cover. On the driver's side of the engine, this hose ends between two of the intake manifold runners (3 and 4). At this end, it connects to a white plastic Y-fitting. This Y-fitting is a good one to replace... about $4, even from the dealer. The other hose on top of the Y-fitting is a short, small vacuum hose that runs to a brass nipple on the intake manifold. You should remove/clean the brass nipple, and inspect (or replace) the hose. On the bottom of the Y-fitting is a short, large hose that runs down to the oil separator... this is another hose you could remove/inspect/replace.

That's just about it. All of the hoses should just pull apart... no clamps or sealant on any of these... just be gentle - I broke the Y-fitting when I removed it to clean (did not have a new one on hand!) Might take a little longer than 5 minutes the first time you pull it apart, but it's pretty easy.

On my '89 it's a large hose with two smaller hoses coming out the top, sticking up between headers 3&4 on the intake manifold. The smaller of the 2 hoses coming out (the one that goes back to the manifold) has a red stripe on it, but I have no idea if that's a universal trait. Just look for parts similar to these:



If you get the flame trap kit from FCP Groton it'll give you everything you need. Just skip putting in the actual flame trap (the round white thing in the picture).
