Who has the highest milage?

[candpliberty]

How about 30,716 miles on a 06? We just sold our car so we'll be putting more miles on the Rennie. We've been retired for 4 years now so going to work hasn't been cranking on the miles.

You all lose on the low mileage.
I got 1,895.

#1 - The rest of your Jeep has 100k on it
#2 - You didn't throw a rod, because 3.7L's don't have rods

3.7L's don't have rods

Correct me if I am wrong, but I fail to see how an OHC engine has rods.

Ah, we may be speaking about two different things...it has connecting rods, not push rods.

 

[mag03kj]

the 3.7 DOES NOT have push rods?

 

[candpliberty]

I thought I'd get in the top bottom three!

The 3.7 is a SOHC engine,it has connecting rods where the term "throwing a rod" comes into play,actually all engines no matter what configuration has connecting rods that go from the crankshaft and piston.

SOHC = Single Overhead Cam
DOHC = Dual Overhead Cam
OHV = Overhead Valve-uses pushrods,can in the block.

yupp

 

[candpliberty]

So the 3.7 has one camshaft per bank of pistons, correct?

Yes,they are located directly above each cylinder head,driven by a timing chain.

 

[mag03kj]

Troy have you tore down the 3.7L?

 

[tjkj2002]

Troy have you tore down the 3.7L?

Nope,have done a head gasket on a 4.7 though which is almost identical.When I pull my engine,for any reason, it will not be going back in.

 

[mag03kj]

lol....409 still???

 

[candpliberty]

May I ask, is it a chain or belt? one or two?

 

[mag03kj]

i'd think chain and just one

 

[tjkj2002]

May I ask, is it a chain or belt? one or two?

The 3.7 uses 3 timing chains,1 each for each camshaft(total of 2) and one chain that goes to a counter balance shaft(located in the conventional OHV cam location).

Oh and the oil pump is located on the crankshaft right behind the timing chain gear,driven directly by the crankshaft.

lol how do you know so much.....?

Been turning wrenches professionally for 14 years,ASE Master Tech for 12 of those years,I either know or know were to find the info.

 

[candpliberty]

So no maintenance on the chain? Not like a belt at 50-60k?
