I bought a 84s in nice body condition with a repaint. I drove the car home started working on it . I replaced almost everything on the car. TT Black sea super bearings, shocks,brakes,oil pan gasket,hoses,ball joints,tie rods,new interior,hood insulation pad,trans mounts,motor mounts, new carpet kit seats recovered many many more things. I just started running the car and coolant is leaking into the oil. Everything works A/C heat etc... I want to sell it ASAP. What is it worth?

if you truly want to sell it you need to post an asking price

With all that work creating such a stable platform, I would venture my 2 cents and tell you to drop a block in it and be done. I wish I had all the new parts you mentioned.

everyone here can relate, and share your frustration and pain. only you can decide when enough is enough, but
you may want to reconsider. with all the great maintenance you have completed, you may be able to figure out
some way to make it work and be happy...….either way, best of luck and success in a positive remedy.

I've been working on this for a year. I'm frustrated.

If you possibly can, it would be far, far better to try to work through your frustration than to walk away at this point. Better for your investment, better for the car, better for your skills. Managing frustration is one of the key skills with maintaining an older exotic car.
On some year models oil in the coolant can be a radiator issue. I'm not sure if '84 is one of those years or not. If it is not that it is likely head gaskets. One of the great things about a '84 is that it is one of the easiest cars to replace the head gaskets on. I recommend doing the job with the motor out, although is is sort of vaguely possible to do it with the motor in. Pulling the motor is not hard, and nothing here is expensive if you can do the work yourself. I would say you are looking at at two or three weekends. One to pull the motor and pull the heads. One to reassemble the motor, and one to reinstall the motor.
But, at least take the time to investigate whether it is a radiator issue.

Sorry misread the OPs info,
coolant in the oil on these engines is usually a leaking HG, to a lesser extent a cracked block or head.
Pull the spark plugs look for a plug thats cleaner than the rest .
also look for rusted electrodes and or green spots on the plug indicating the green coolant if thats what color coolant you have.
the plugs will give you the most info.
also look into the cylinders and see if you find any coolant

Step back, take a deep breath, and consolidate some thoughts. The Most Likely cause of the coolant in the oil is a head gasket leak, but it could also be as easy as the oil cooler in the radiator leaking. Is there oil in the coolant? The radiator comes out relatively easily and goes to your favorite radiator shop for a pressure test on both the coolant side and the oil side. They do this stuff regularly, and will be able to tell you rather quickly if there's a leak between the two systems there.

Head gaskets aren't impossible to do in the car but they present a bit of a challenge just for access. By this time in our cars' lives, engine removal gives us access to some more stuff that can use PM attention, like crank seals and the like. And cleaning. And anything that has not been changed under the intake. Maybe some crispy wiring.

Regardless, you have a year of fun and over $11 already invested in the car. At this point, unless there's a cracked block, you are more than 90% to the finish line. The last 10% wasn't expected, but in reality it's hardly a deal killer. It's gaskets and some cylinder head refurb. More: Mark at 928 International has lately offered a 50%-off sale on used bits starting around Thanksgiving and lasting until they take off for the Christmas holidays. If you pull the heads and find a crack, your fallback is a used engine/long block from his collection.

Meanwhile... The only reliable way to recover $$ and sweat equity in these cars is to drive them. Plan to do that, or be mad for the next few years about selling it. Regardless, decisions made in the haste and heat of battle tend to be a lot more tactical than strategic. You have the luxury of being able to put the battle on pause while you revise the strategy. Take advantage of that luxury.

I worked on my Schwartz car for 4 years before I got to drive it twice (2X!!!) before I found out my head gaskets were bad. (See, it's not as bad as you think. )

If it ends up being the radiator oil cooler, you can buy a new radiator from Roger or Mark, or I have some extra radiators laying around that I can make you a pretty good deal on just so you'll keep your car. You need a radiator with 2 coolers, right?

I spent about 3 hours yesterday failing to get a fuel pump to stop leaking at the check valve yesterday. And that was after discovering that the (5-speed) car had come with an automatic car's rear crossmember, so the transmission mounts are an inch forward of having a prayer of lining up with the crossmember slots. So I have to swap out the rear suspension onto a correct crossmember.

It's a hobby car, I still have the boring commuter car to get me to 928Intl for parts. Not the end of the world. Just step back and smile, 'cuz Porsche problems are 1st world problems.

Oil in coolant....likely an oil cooler in radiator, since there is more oil pressure than cooolant pressure.

Coolant in oil....oil cooler leaking in radiator not likely, for the same reason as above. Almost always head gasket...or worse.

What if it's both. The same color mix comes out the radiator and the sump?

gomez123

I don't have a oil cooler in the radiator just a auto trans cooler.

Speedtoys

You sure? You should have both coolers in the radiator...

soontobered84

You should have oil cooler lines on the left side of the radiator and trans cooler lines on the right. If not, it's time for an upgrade.
