If you attempted to run the engine with the valve train improperly aligned, you may have caused valve damage to your head, as this is an interference motor. This would definitely affect your ability to produce a lot of compression within the cylinder during testing and could be the reason why it's not running. Unfortunately, about the only way you'd be able ...
Does my hypothesis sound reasonable?
What doesn't sit well with me is that the engine has already been cranked a lot (when the cylinders were flooded). Regardless of whether the engine started, shouldn't that be enough to relubricate the walls?
Compression can be lost through:
curvature in the cylinder head
leaky head gasket
gaps between the ...
The scratching sound is from the starter gear. Each time you turn the key the following actions happen:
A relay is powered that triggers an solenoid
The solenoid moves the gear from the starter motor to engage a sprocket on the engine
The starter motor starts to turn
The scratching means that the started motor gear does not correctly engage the sprocket. ...
If possible.. try drilling a hole.. big enough for a large screwdriver and a replacement nut to fit through.. in the side of the subframe, in front of OR right next to the area where the captive nut is spinning.
Stick the large screwdriver through the hole using the hole itself and the flat of the screwdriver as a lever to jam the captive nut to stop it ...
I encountered a similar problem some time ago changing a wishbone on a Mk3 Golf. The solution was to replace the subframe with a good second hand unit purchased cheaply from a vehicle breakers yard which was thoroughly cleaned and painted before fitting to prevent corrosion.
Depending on what access is like, you could potentially cut an opening in the ...
There is a gasket that sits between the master cylinder and the brake booster. It is a thick rubber gasket that fills the space between the two parts and fits snugly around the master cylinder shaft. part #- 46185-SE0-003
