Speaking of Plastic Cooling parts...

Most of you know of this part, its the 2 hose piece that goes to the heater core through the firewall....Make sure you do it, i got lucky it started dripping in my street and i smelled it before i left. So for all you swappers or anyone over the 100k mark really do it when you get a chance or be ready to pull things apart. I was told to do this when i had the motor out(i didn't) it took about a year and a half but it went out on me.

I probably didn't have to go this far but i did a little cleaning as well as a water pump and thermostat housing, and i also found another plastic cooling piece that was broken its for the M5x family of motors though, it connects 2 cooling hoses together replaced that one with a metal piece now.

Its cool though as I'm redoing my whole vacuum system and really cleaned the motor i might get the knock sensors done at the same time, but its a bit pricey right now.

Cheers! and happy new year!

So just curious i have the Intake manifold off now, I have already cleaned the ICV ordered all new vacuum lines or bought generic lines from auto zone, de-greased most of the motor, replaced the two plastic cooling pieces, and inspected the hoses.

Other the Knock sensors( currently not throwing any codes once in awhile a random one at 3k rpm for a split second) which i cant afford to do is there anything else i should do?

Starter, alternator, valve cover gasket and clutch are all brand new less than 8k miles.
The seals on the intake manifold look good, i even ordered the 2 plastic vacuum connectors( the one under the intake manifold and the one on the valve cover)

I feel like I'm missing something and I need to do more?!?

Help lol
