Hi guys - this is my first proper post and I’d welcome your advice.
I bought my ex-Colorado ‘74 2-litre about 18 months ago and have concentrated so far on a total rebuild of the engine. The engine is back in and I’ve just completed the cam burn (scary). I’m now left with a couple of oil leaks from the pushrod tubes at the case end, both on cylinder no4. The heat exchanger was a complete pig to fit, and the manifold is actually touching the pushrod tube on No 4. Is this normal? The tubes are new but are exactly the same diameter as the old ones. I’m thinking of putting a bit of a dent in the tube to give it some clearance passed the manifold. Any suggestions welcomed! Attached thumbnail(s)

Sometimes the copper gaskets fall out of place when installing the heat exchangers. That would also cause an exhaust leak.
Others here have suggested putting a drop of super glue on the copper gaskets to hold them in place during the install. I tried this the last time I had mine off and it worked perfectly. |
