Rebuit 350 CID
 

Good morning, thank you for your attention. We are restoring a 350 CID 5.7 TBI engine, we have some questions for experts.

1º. - In the workshop manual of this motor, it indicates that in the screws of the cylinder head is necessary to put paste, is it completely necessary? I've seen videos on the internet that don't put money in it. How can I do this? Can I cut it short?

2º. - When we have put the pistons in the cylinders we see small marks, very small, is it normal for them to come out? see photo: maybe it was due to a lack of lubrication when introducing it. (See photo)

3º. - The camshaft at its ends is limited by a plug on the gearbox side, at what distance should it be placed because we don't know where to put it? (See photo)

On the front side of the engine, the camshaft on my engine does not carry this part:

The block has a shape to put it in, is it necessary to put it in? When we disassembled the engine, it wasn't on, do I have to buy it to put it on? we understand that the chain acts as a guide so that it does not move.


Thank you very much.
