Hello, I'm Jason. I will do my best to answer your question quickly and accurately using the information you have provided.
my first question back to you is when was the last major service performed?
hopefully, you'll be able to access the chat function
if not, I can switch to email format
are you able to see the question I posed back to you?
I don't know?
ok, so no history or major services, or cambelt replacement?
history of major services
Seems as though you're possibly having some problems with the live chat
I will give you my recommendations, basing them on a completely unknown service history of this car
The absolute first thing I would have done is a complete major service, including timing belt/water pump service
Here is everything needed for this service: http://www.ricambiamerica.com/product_info.php?cPath=40&products_id=263848
Expect to spend about $3500-$5000 in labor depending on the service facility you use
then expect to spend about $2000 for every 12k miles after this service is complete
