Some Problems

January 15th, 2007

By now i have more than a year driving my car, when we assembled the engine, we reused as many parts as we can, sometimes this is good, sometimes not, in this case it wasnt so bad, but not really good. When we sended the heads to be reconstrcted, we discovered that they had something that in spanish we call “guias sobremedida”, in english is something like bigger valve guides, cause my engine was a refurbished unit from Volkswagen, they fixed the case and the heads, in the valves guides case, they made the holes were it fits bigger, thats why the guide’s exterior diameter is bigger than stock. Here find that kind of guide is really hard, but i finally found 8 and fixed the heads. Another common fix here is, when the spark plug hole loose the threads, you make the hole bigger and then make new threads and intsert what we call “helicoide”, it is a bronze piece with a thread in the interior for the spark plug and one in the exterior that bolts to the big hole in the head. My two heads had this, but the one in the cilinder #1 was pullling the spark plug out sometimes, and it finally stoping working, so i disassembled that part and by now im triying to fing some good heads. Im going to change them, cause i have two 1300 Heads, bored to 85,5mm to work with 1600 cilinders, this heads have smaller valves, and the combustion chamber is smaller too, this make the CR (compression ratio) go up, making the engine run hotter and it doesnt work exactly how it should, i didnt know that at that time, and now i have to pay the price. Cause my engine is single port, and i want to keep it that way, i found two old single port 1500 heads that im waiting for the shop to fix the guides and put new valves on it, ill show you the new heads and the old ones when i got them here again!..

By the way, now i have some of the parts im going to use in my 2110, ill put some pictures soon!.
