now im wondering if the turboscoop has made more volume therefor maybe i shuld remove a shim ?
what do you think
thanks..
Take the engine apart and check for damage. Usually whan an engine starts to wear badly the internal parts can rub and create microscopic particles of aluminum. This aluminum gets on the glow plug filiment and will cause it to blow rather quickly. Even repetedly.
I'd especially look for wear on the conrod (big end and small end), crankshaft, and backplate as this is usually the suspect area.
Many times an engine will run it's best right before it blows up, so this is definitely a possibility. Take it apart and let us know how it looks inside.
