Sprung a lil coolant leak and tracked it down to the driver side heater hose which was in contact with the back corner of the intake manifold(AEV). Things are so damn tight behind there I can barely get one hands fingers back there. Ive attempted to RTV the pinhole but am wondering if anyone else has ecountered this? Really hoping i dont have to lift the body to get back there...
s come across this issue?
Thanks
I saw this as a potential problem on mine so I wrapped with another piece of hose where it touches. I would try and bend that metal nipple forward a little bit but don't kink it. My manifold was off to repair some oil leaks in the valley, I think it was PCV grommets. Pain in the Ass place to put them!!
I wouldn't trust trying to patch that hose as there is too much at stake in the engine. You might be able to shove another piece of hose in there and Zip ty it for prevention sake.
I miss the old days when you could just about crawl down the back side of an engine between the firewall and bellhousing. Have any friends with really small hands that are mechanical? Otherwise, you'll probably have to start removing things to get access.
Thanks for the replies and suggestions. I'll see how the RTV holds up,if not I will try flex seal,looks like they sell it at a local store.
Worst case may have to remove the intake.
Flex seal was a total joke. I wouldn't trust it on something like this. You need to plan on replacing the hose and wrapping it with pieces of the old hose or something that will prevent this issue again.

yeah this will be temporary until i have time to remove the intake.
removed the intake manifold and glad i did. the heatshield on the wiring that runs between the block and intake manifold has melted a bit. so will reshield it and replace the rubber gaskets in the intake manifold and give things a good cleaning. oh yeah, got that friggin heater hose off to. any other advice or maintenance that should be done while the intake manifold is off? thanks
Check those rubber grommets in the valley. I think there are PCV. Mine leaked and required removing the intake to fix. My valve covers leaked as well and the right one is a total pain to replace as you can see, Most engines these days are pretty leak free so I was just unlucky. Good job on the fix!
