Lifters/TDC/Oil pressure gauge

[jazic3.4]

I have taken my 3.4L out of my 1992 Z34 and it is currently on an engine stand. I am changing the Head gaskets because they are blown. I am replacing every gasket and seal that I can since I will be having it all apart anyway. Here are some questions for anybody:

 

1. How do you keep the lifters in the cam carrier from falling out of the bottom upon cam carrier removal?

 

2. I noticed that when I set the cams to TDC, all of the factory timing markings align except for the rear cams. They are off by a tooth. When I install my new timing belt, do I have to align the rear cams by the yellow factory markings just like the front cams?

 

3. I would like to install an oil pressure gauge in my car, where would I connect this gauge on the engine? Which sensor would it connect to? I heard that I have to replace my factory oil pressure switch sensor into an oil pressure sender sensor before I can consider this. Is this true?

1. Use a towel to catch them. They should fall into the towel in the same patern as in the cams

 

2. Don't use the timing marks on the cam cogs. Remove the valve covers and get make some cam hold tools. Remove and reinstall cam cogs.

 

3. Yes you need to replace the sensor. It will thread into the front of the block under the exhaust manifold. Make sure it is an oil hole and not a coolant hole.
