348 Engine repair thread

Ohh and when I put the crank pully on, the timing mark on the pulley (little drilled hole) is dead nuts 12 o'clock with the mark on the block.

 

Great thanks for the measurement. I need to make one now as they are NLA and no one has them.

Yep I see it now, the inner key keys to the bearing that rotates with the crank, no wonder it was lined up . Regardless when calculating true TDC with the wheel and I slip the crank pully on, the crank pully mark lines up with the block mark. Good to know that TDC mark on the crank is actual TDC on mine at least. I'll still precision slip mark the crank to the block for easy reference when the pully is off.

 

Up next while I wait for the heads is rear shock bushings. They're definitely more collapse than front were probably due to the weight. Will do the top rear control arm bushings as I have those new in a parts bin. The lowered are a different part. Lowers can be done easier with engine in car. Getting the shock back on should be a royal pita even with the springs compressed. Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login

May as well do control arms while I'm waiting for the heads. They come out in pieces since there's no shoulder to put a sleeve to press them out. You could cut the shoulder off the bushing etc and then try to use the sleeve. But at the end of the day it's faster just to put a slit in it and knock them out.

There's the bushing out in pieces next to a brand new bushing and the second picture is the outer bushing sleeve out next to one still in the control arm. Image Unavailable, Please Login Image Unavailable, Please Login

Item of note, I spent time to remove a rubber insert without destroying or melting it. As you can see its in great shape. The bushing rubber is not under pressure, the bushing has a sleeve which is supported with steel washers inside the housing Thus the bushings are riding on the washers. Unless yours are visibly dry rotted there is no need to change them. I want to refinish the control arms as they have a slight bit of corrosion around the bushing flanges.

 

Second, I got one of those new fangled water pumps. The locating pins did not fit my housing. Its not a tricky alignment thing, I knocked them out and they physically do not fit. Few hundredths too large. So knock them out and swap them, problem solved. The pins from the new pump go into the bin. Water pump want together smooth after that. Always something... Ordered Stainless bolts from McmasterCarr they are M8 1.20 x 50mm and 55 mm. Two of each they come in a pack of 10.

Still waiting on heads... Running out of nickel and dime things to do. So I will put on new shock springs and shock collars and rubber spacers. Waiting for those too.

 

It was SO easy to resolve I just assumed that was the process. Figured someone else down the road may not realize you can just swap those bosses so I figured I'd mention it is all.

New water pump in, all new hardware new thermostat new gaskets. I use metric fastener torque specs for the m6 and M8 studs. I lightly oiled. Image Unavailable, Please Login


Lots of TDC marks.

Check out the gangster new suspension bolts I bought them from Daniel about 2 years ago. Knowing one day this day would come. You know because someone else besides me touched the motor. Only reason that happened actually is because of the time I bought the car we were living in a high-rise and I had no actual garage.

Dang good call, its together already. I am guessing when I pressure test it it will reveal if its not true. I would not ream the housing holes, I would turn down the dowels first, or swap them, that housing the pump bolts to is spendy and may need the OEM water pump one day.

 

Oh no I have the dowel pins in place I just used the dowel pins from the original pump and put them in the aftermarket pump and then assembled it to the housing. Dowl pins are intact but the original ones not the ones that came with the pump. Snug fit they are.

Excellent point, great explanation.
