If you replace the chain be sure to get a good double roller one.

 

Whats the difference ? The stock is single and i have seen them go 250,000 + miles ?

 

On these engines the computer controls the timing. There is no adjustment with the distributor for timing. Turning the distributor adjusts the fuel sync. Once it is running you can use a Snapon scanner to adjust it or take it to a Dodge dealer to have them set it. So line up all your timing marks on the engine stand and then install your distributor and lock it down.

As for the intake manifold I have always used the rubber gaskets with no issues. You have to put a dab of silicone on the corners where they meet the side gaskets.

 

Does a 5.2 have the same fuel injectors as a 5.9 ?

 

Then why are there timing marks on the front timing cover ?

 

Stock singles stretch over time and it can affect the timing.

IIRC yes they do, the 5.2 and 5.9 are the same motor with some slight differences in them.

 

See bold.

 

The stock "chains," im being generous even calling them chains, will stretch out by 60,000 miles. A double roller is around 40-50 and will have you set for life

 

Timing marks are more than just for setting timing with a timing light. If you don't have a repair manual down load one from the DIY & How TO section which has a link for manuals. Also try doing a search for threads about rebuilding your engine as there have been a few that showed how to line everything up. Here is my link for my rebuild, go to page 17 and you can see how I lined up the slot in the gear for the distributor. It has to point at the first bolt hole for the intake. https://dodgeforum.com/forum/2nd-gen...-cheap-17.html
While your doing this you also have to have the crankshaft and harmonic balancer lined up with the marks on the front cover.

The other thing to remember is that Mopar when they redesigned these engines do so while trying to save money too. Your front cover is missing the fuel pump hole and that is the only difference between it and the older 318 covers. It is just like you could use the old style valve covers. They don't have 10 holes like the new ones but they would still work. One of the reasons for the redesign was that the valve covers use to leak so they added more holes to clamp them down better.

If you have questions about lining everything up ask and there are plenty of folks here who will help you out. I use the factory repair manual plus the How to Rebuild Mopar Magnum V8 Engines, got mine from Amazon.
It is a real good book and walks you thru the whole process and gives you tips along the way too.

 

Well got it all together and no start ? It has no fuel pressure or spark ? I used everything off of my running 5.9 ! Coil, cam sensor,crank sensor, intake, fuel rail, injectors and it doesn't run ? I didn't use my distributor ! Any ideas guys ?
