Re: Losing Coolant and dropping oil pressure gauge
I also had one of those recently. Drove me nuts until I noticed my
battery was covered in coolant. Same deal a mini pin hole that would
only open up at highway speeds when it was really hot.

Re: Losing Coolant and dropping oil pressure gauge
Coolant can leak directly into a combustion chamber after the vehicle is
warmed up, without any showing up in the oil. As Chris says, a pinhole leak
can do the same. The folks at your garage will likely never see what is
going on, unless they allow the vehicle to run for a good time while they
observe it. You will be paying their no doubt high hourly rate, to have
someone watch the vehicle, but that is how you find problems like this.

Re: Losing Coolant and dropping oil pressure gauge
Not only does the engine have to be at full temp and pressurized but at temp
long enough to get the hoses fully softened.
Ed had a tiny little split hidden by the radiator clamp. Turns out the hoses
were factory from '96. It is lucky he didn't have to walk home...

Re: Losing Coolant and dropping oil pressure gauge
Back from the dealer, they say I have a cracked head and the crack is
visible from the oil filler hole in the valve cover. The service
advisor said that they have seen these before in a range of motors that
my year falls in. This is where the coolant is going and that I am
burning it he says.
He also ran a mechanical oil pressure gauge to the sending unit and the
engine is 9 psi at idle which he thinks is below normal and that there
is bearing damage.
He is recommending a new long block at $3000 plus installation ($1500),
he also mentioned that they could find and install a used one as well
for around a $1000, installed for $2500
Not to mention the rear end needs an overhaul with new bearings as
metal is coming out in the oil.
Nice xmas present.... thoughts anyone?
