Finally started, but still need help

[otif]

Okay, so you guys have helped me in the past. I have a 1982 Euro Spec with the 4.7 litre and a 5-spd tranny. I have been working on it for quite some time, and to make a long story short, I finally got it started but now it spits (shoots) oil out the tailpipe! Has anyone else ever had that problem? I really need some help here.

Gotta get this thing running right so I could get to work on paint and interior. Any advice will be welcome.

Thanks

Hey Otif, What did you do to it? Did you have the plug wires off? Intake off?, give us some insite

[otif]

As a matter of fact, I did have the intake off. I pulled the plenum, runners, and entire CIS system off. Other than that, I have not pulled anything off.

[DPW928]

My 79 euro did the same thing when the valve guides went bad. Pull some of the intake tubes and look at the backside of the valves. If they are caked/wet with oil it is time to have new guides installed.

One other possible reason, would be that the A/F ratio is set too rich and raw gas is mixing with the exhaust residue and spitting out black liquid/soot.

[bwmac]

If it is not popping to bad let it run a bit incase its a (dose yours have lifters)
Lifters will bleed down over a few weeks if it hasn't run.

While its running, spray some WD40 or something along the intake gaskets. if it clears it up momentarily you have a intake leak. If it clears by itself it was a lifter

[Danglerb]

When I first started my Euro S after maybe a year of not running it took about half an hour for the lifters to totally quiet down, but it was a steady decrease in lifter noise.

How do you know its oil? Very common is moisture condensing in the exhaust system and water spitting out when its first started (very dirty water that can look like oil).

[otif]

Sorry for the delay in getting back to you. Too much work and too little play.

I'm gonna go ahead and pull out some of the runners and take a look at the valves. As far as letting it run, the amount of smoke is RIDICULOUS. It's definitely oil. I took some pictures, but I cant get them out of my camera here at work. I'll do so later today and post them. You guys will be able to see hte amount of oil that came out of here. Another thing I noticed is that the oil was actually leaking through the exhaust (through some flanges).

If I see there is anything wrong with the valves, I should just take out the heads and take them over to a machine shop and get them re-done, right? If I need that, does anyone know of a good one in Miami, FL. I used to go to one a while back, but that was for my Z's, but never for a porsche.

Thanks for all the input!

When the guides went on my euro a shop in Tulsa repaired them for around $280 per head. New guides, reseat the valves and resurface (not mill) the head and cam carrier surfaces should be the minimum for the rehab.

[otif]

I pulled out the CIS system in preparation of removing the heads (should I pull the engine for this?), and I noted that there was a lot of fuel in the (sorry, I don't know what it's called) piece under the plenum that the fuel distributor connects to. This fuel was very dark and oily. The runners all had a lot of oil residue on them. Is this normal? Any input on this would help.

[MPDano]

Oil in Spider Legs are normal. Remove and clean out as best you can. Mine also had a lot of oil in the part your talking about. i just used mega carb cleaner and drained it out as best i could. FYI, all the CIS stuff was off the engine when I cleaned it up.

I do advise you to remove the engine if your gonna pull heads. Some have done it but I personally vowed to never do it again.

Ralph,

Oil in the valley is very common, but fuel isn't. Is there a fuel line leaking around the distributor or injectors? Does your engine oil smell like fuel also? If so, there could be a blowby problem or leak in the vent system.

It sounds like he's talking about that big bellow looking piece of the CIS that actually sits on top of the valley. Would fuel collect there if someone were trying to pour gas into the throttle body and it getting collected there and mixed with all that oil sludge?

If someone was priming the system, fuel would collect in the lower plenum, not under it as he stated. Either there is a leak in the fuel system (injectors, lines, fuel distributor, etc) or there is fuel in the crankcase and it's being blown out through the venting system and leaking into the valley.

That's exactly what I'm talking about. I didn't pour fuel in there, but I did spray some starting fluid. Not enough to have so much in there, though. Plus, starting fluid would evaporate, right?

BTW... That is a real sharp intake on your car! I know that I'm nowhere near this yet, but what kind of paint did you use for that? I was thinking about maybe powder coating mine. Is that a good or bad idea?

Hopefully, I'll have some time and remove the engine this weekend. Then I'll get to work on the heads. I have not been this excited since I pulled my first engine (out of my Z)! That was 20 years ago!!!! Anyways, I'll take some pictures and post them when I'm done. Hopefully I won't run into any snags, but if I do, I'll be posting more questions before posting the pictures

If anyone can offer some tips for engine removal, it would be highly appreciated.

Thanks for all the input!

[MPDano]

I used High Heat Wrinkle Finish. I think Powdercoating would be awesome on yours. Just make sure you mask off the areas where the gasket and coupler areas are.

Ralph,

Starting fluid is ether so it wouldn't cause the gas smell. It is common for blowby from the crankcase to get into the upper and lower plenums. Another possible source of the fuel is from the cold start valve. If the engine is cranked, but not started, you would get gas into both chambers.

[otif]

Here are some pics of the oil that came out the exhaust pipe when I got it started. It looks like there is water in the oil that's in the bucket, but that's from some rain that day.

Otif,
Oil in the bucket, confirmed!
How about the oil on the ground...in California and other states we get in trouble for this.

Here too.

I got into more trouble though for the oil on my fence!
