Project Update

Well, here is the damage.

Turned out that 4 of the 6 guides are either partially or completely broken. As you can see from the pictures, the broken pieces are all over. some small pieces were also found in the oil pump intake openning. Luckily there is a filter screen. Only 2 guides (lower passenger side and tensioner guide) were in tact but you can see the wear.

Driver side exhaust valves are all bent but there is no damage to valve guides, head or piston. All cylinder walls look very good.

The heads were sent out for rebuilt with 4 new exhaust valves, 8 exh. guides & all stem seals and a machine job.

Everything is now ready to be put back together and so far, total cost for parts and head rebuilt is around $1,300.

So far, here is a list of parts that will be going into this engine.
Rebuilt Heads
Timing Chain
Timing Cover O-Rings
All Timing Chain guides
Lower & Upper oil pan gaskets
Front & Rear Crankshaft seals
Intake Plenum gaskets
Throttle body gasket
Water Pump & gasket
Oil filter stand gasket
Oil pump chain rail
Timing chain tensioner and gasket
Oil filter
Upper and lower radiator hoses
Expanion tank cap
Cam oiler kits
Left and Right Head Gasket sets
Valve cover gaskets
Used valve cover

Are there anything else I should replace while I have the engine out?

More progress and pictures to come later.

Thanks for the input.
