oil leak?

[warrenrhen]

I had my 79 Fiat 124 down for a while, desmogging it, installing headers, replacing intake manifold and carb I just fired it up today since doing the work. There's a major oil leak on the right side front. Looks like oil running out the holes that held the smog pump bracket. Is this possible? If so, is there a certain length bolt I should put in there so I don't restrict oil from going somewhere where it should be going? I also didn't plug the holes in either side of the head that take the exhaust gas from the exhaust manifold to the EGR valve because I figured there should be nothing traveling through there since there's headers on one side and a single plane manifold on the other therefore it's non functional.

Are these holes in the head or in the block?

If oil is really coming out of unused bolt holes, then you would need to use a short bolt and a copper washer or possibly thread sealer.

bottom of the block on the right front. As I said the holes from the smog pump bracket

Do you mean these ones?


If so yes you need to seal them with short bolts and thread seal

Drummond, that engine is so clean, spotless! Did you just build it? Running?

Same thing happened on my car... I had an AC compressor bolted to a bracket attached to those holes. Ripped that right off and promptly sprayed oil out of the holes. D’oh! Right now I just have the bracket bolted back on to stop the oil leaking out, but I got some bolts and copper washers sitting in the “parts to install” bin in order to save some weight.

Yes just rebuilt 3 years ago
this was a pre start up pre oil pressure spin up before starting. I heard this sputtering noise and looked down oil was pouring from the holes
I couldn't believe they tapped into the oil chamber??

They did the same thing on the exhaust manifold.

These are good engines all things considered, but this BS is almost unforgivable.

I ran into this after my last rebuild. Also, I found out that the engine bracket has some blind tapped holes and some through holes into the block where hot oil drips down and seeps through these taped srews. I need to clean these out and apply sealant.
