    eater Core questions (yeah as always)

    I'm having a problem with my 02 . Both heater hoses are hot but air coming out vents is barely warm . Doesn't anyone have an old core that they can saw into & determine once & for all if the coolant can bypass inside the core or not ? I breezed through this thread this time so I'll apologize in...

    PCV/Misfiring

    Sounds like a compression test is needed . 4 & 6 are adjacent cylinders , possible blown head gasket . White smoke / steam is also an indication of a blown head gasket . You can get a block test kit at NAPA for around $40.00 bucks that will tell you if the coolant is getting exhaust gases in it .

    External Transmission Cooler

    Just went out & looked at the 02 & 05 . It's raining so I didn't examine closely but it appears as though the metal lines from the transmission transition to rubber hoses at the front of the engines with just hose clamps on them . Perhaps it will be a fairly easy swap . If anyone has made this...
