4 corner steam vent line help
I'm needing a factory 4 corner steam vent line for my swap. Does anyone sell them new or do I just need to search the junk yards? I see one for sale on Ebay but I would think there would be more.

im assuming your referring to a LS ....junk yard should work easiest...but they do sell the banjo style fitting for the steam ports...I bought a set of those and did my own plumbing with stainless tubing

Yes it is for a LS and I thought I was posting in that forum but got back on this one somehow.
Thanks. |

You really dont need a 4 corner system . Gm stopped putting them on somewhere around 04 . I think it was developed mostly for the corvette or performance cars that the engine sit level front to back . If an engine was to sit level ( corvette drive line ) it could hold some air in the rear corner and the vent line allowed it to escape . If the engine was at a 3 degree angle ( most all swaps )down any air would migrate to the front to the vent lines . These lines are not for cooling . They will not move enough coolant to do any good . They will remove any air so you have as much coolant contact to the head as possible to eliminate and air pocket and hot spot .
If you are setting your engine up to be level front to rear I would suggest a 4 corner system . If not the fronts will work just fine . I would not spent the money on a 4 corner system . All this being said , The op can find the oem 4 corner system on ebay . Expect to pay 50 to 60 bucks . Junk yards would be a crap shoot . They have not put these on vehicles for more that 10 years . There is a lot of aftermarket stuff out there to set one up . |

Agree....my 2000, 5.3 did have the 4 corner setup. When I opted for the carbed setup, the lines would not fit under the intake? A call to Carshop, & the response, was no longer used. A look on my 02 , & no they were not! My engine in the 69 is set @ 3 degrees....& no issues;) Longhorn

I did go on ebay and found one there.
I've read that they are not needed and the engine angle does make sense. I just figure there are 4 ports so I might as well use all 4. |
