i figured this was coming sooner or later. started the 99 today and after it got up to operating temp, i could smell a hint of coolant. took me a while to find it but i found a very small pool of what appears to be coolant under the lower intake, between the heads, behind the water pump. is this a common place for these intakes to drip? does it crack underneath?
dumb question here but there is 2 parts to the intake a PI 4.6 right - upper and lower? if so, how do i replace the lower if thats whats leaking? everything in summit shows the top portion of the intake....or maybe thats all i need?
i found two intakes. one is a Dorman the other is Ford Racing. i much rather have the FR because in the description it says the base material is aluminum. the Dorman says hard plastic.
Dorman 615-175 - Dorman Intake Manifolds - summitracing.com
Ford Racing M-9424-P46 - Ford Racing 4.6L Performance Improvement Intake Manifolds - summitracing.com
now, do both of these already have the upgraded aluminum crossover that i want ?
one has the EGR ( dorman ) and the other ( fr ) does not....do i need that?
heres a pic i attached from my cell of where the leak is. its hard to tell from the pic, but the small amount of coolant is where im shining the light.
thanks for any help
