Thought I would open this to a new thread to get a broader audience.

I need to remove my Oil pickup to check for debris just to be sure it is not any swarf from cleaning up my block face on my head swap. I have 2 options. Endoscope check it all including down the pickup. Or better to remove the sump/filler pipe.

the Sub frame is right in the way. so the engine needs lifting (not an issue) but can it be got to either sump out or just resting on the subframe? I have small hands an arms so could get to the oil pickup nut?

Thoughts. All my parts are ordered and hope to have the car back on the road ASAP.

Thanks

I sure as hell would not wanting to be removing the sump with either the engine in the car, or the suspension cradle in the car. That applies to most similar vehicles too.

Whichever is easiest to remove. If the body is in the air and engine suspended from above then you could try and drop the cradle as much as possible to give you room, rather than trying to lift the engine up, which will only go so far with the gearbox still attached.

But underneath it will be a messy affair, as oil will drip everywhere, and onto your head lol.

Engine removal isnt a massive task in most cases, and allows for all work to be done pretty easily.

You could consider blowing down the pick up with an airline after flushing/draining the engine oil etc. Then use your enderscope. Do a dummy run on installing the pump to the pickup to see if it slides home easily, use vaseline, lol. I don't think you'll get an ls1 sump off, subframe in situ but somebody may say otherwise.

It's what I thought. I'm thinking the endoscope tocheck and an air line down to clear the mesh screen.

Right pain. Really don't want to pull the engine. It's a pain with the headers they are so tight on the drivers side.

I'll see what I can do and will check the oil once drained to see what it looks like. Also peel back the filter and take a look. This could let me know if I need to pull it all.

What are you trying to check with regards the pickup pipe ?

If the relief valve was stuck...that is the problem. have you removed the plunger and inspected it yet ?

Was there a block skim, head skim involved? I can't remember.

I have removed the plunger it seems to move fine and no debris. The spring felt weak though. But to be sure I want to check the screen for any debris just incase for peace of mine. Other than that no other reason.

It seems to coincidental that I fail that soon after major works. Although it could just be.

Like Stevie said, major ballache in situ. When we have done it (and i wouldn't do it again) ive lowered the subframe to make space to get the sump off.

Take it out if your worried, or just stick a new pump on it. They fail for no obvious reason. Might be debris, but i doubt it.

There is no sign of debris. Just paranoia. I'll check with a scope and the oil. If it looks ok I'll move on.

As said. Just all a bit to coincidental

Maybe coincidence...but I'd just replace the pump and rebuild.

If you were really concerned...then it would be engine out for further inspection. But after seeing the plunger stuck...I just see no point in doing that. Sometimes it just happens.
