Haliburton Forest. 8 hours round trip! Trails were good. They have lots of snow there!

Was that u last Thursday with the loud exhaust ?

Had a mechanic buddy who works on race cars drop off some some heavy duty hose that was lying around the shop. It's universal and resistant to oil and several fuel types. It's slightly larger in diameter and holds a more than enough pressure than the 5/8 inch heater hose I had on it that deteriorated and leaked everywhere. I'm hoping this is the final round. I'll be testing it out in Quebec this weekend.

I am going to use airoquip #FCU 1206 starlite hose to vent the tank. It's lightweight, flexible, heat and petroleum resistant but a little expensive. I would like to dump into the muffler outlet at a bit of a angle to help siphon out air. It shouldn't freeze shut anyway. Any thoughts on this?

Dumping oil vapours into red hot exhaust stream seems like a recipe for a fire to me....At the very least the hose will melt.

Did it on my race cars all the time. Had a check valve at the header collector. Crankcase ventilation at WOT.

seems like one in a million chance a tank would be cast completely closed like that....

Do these engines have that much blow by? I'm new to the 4s world so it's a honest question. I didn't think the muffler outlet would be glowing hot. The hose I mentioned is pretty good stuff, racecars commonly vent into the exhaust. You're probably right though.

Mine dumps out just behind the muffler(lots of pics around here) near right toe. And I often think about it when lake running. These turbos spit out alot more heat then a NA sled IMO. Not too mention the odd flames here and there. It wouldn't take much to ignite IMO.

I slit mine at a very large angle(aimed rearward) to prevent freezing of end in POW.....

27 miles .... that's really crappy ... I was there last thurs , there was a srx breaking in sled . It Had a mod muffler, we could hear his sled miles away & he was only part throttle. I would be interested to see what muffler it was ,

 

[Yaahoo]

What about adding a slit to the hose on the inside Incase it does freeeze up?

Yes mine also has a slit for failsafe but has never plugged up with the long cut at end. Most of this is all within this thread from last season.

Oil doesn't ignite very easy , unless really hot or satchurated with gas . Even then it burns slow . Older cars have crankcase pressure ( blow by ) dumping into the headers .
