Hi, My Name is ***** ***** for posting your question to just answer. I am a ASE Certified Master Auto Technician with 20 years experience. I am confident we can resolve your problem together.Please remember I don't know your skill level. I can't see, smell, hear, or touch the vehicle. It may take a few back and forth replies to get to a satisfactory resolution.I also try to give all of the information you may need expecting a positive rating.

Was there anything happen leading up to this? Have you checked the oil? DO you have an oil pressure gauge on dash or a light?

Valves rattling could ben starving for gas dont no
Expert:  Tool Hut replied 1 year ago.
Could be fuel pump. I am more concerned about the rattle. The 2.5 was very sensitive for oil and overheating problems. The 87 had piston problems.
Expert:  Tool Hut replied 1 year ago.
The fuel pump will not cause a top end rattle.
Customer: replied 1 year ago.
Think could be bad piston I was inside that motor there was no sign of that that motor was very clean inside only sluge was stp in the bottom of oil pan clean it out

There is also a possibility that it could be the EGR valve stuck open. That may account for the rattle. Try tapping the top of the egr and then try starting it.

It has been a couple of days since I have heard from you. Do you still need assistance? I have also noticed that I have not received a rating from you. If for some reason you question did not get answered please reply. I am only compensated for my time when you leave a positive rating. Your understanding is appreciated.
