This is a 1991 Volvo 240 wagon automatic transmission with 145,000 miles.
About two years ago I had the timing belt replaced by a general repair shop. I provided the belt kit and the seals (FCP Euro, lifetime warranty). Starting several months ago I've been noticing an oil leak from the front of the engine coming from under the timing belt cover which is becoming worse (have to keep adding oil) and blowing back onto the engine compartment. I loosened the upper plastic cover and discovered that there is a film of oil on the outside of the timing belt. I presume this means that a seal(front camshaft seal?) is leaking. It leaks only when the engine is running. I plan to repair this myself.
QUESTIONS:
1. How many months can the timing belt last before it self-destructs from oil contamination?
2. Is there more than one seal under the timing belt cover?
3. Given that this could be the result of faulty installation, or even a properly inserted seal that just happened to fail, should I be concerned about what brand of seal to install? (I plan to buy the kit from FCP Euro and return the previous one under the lifetime warranty.)
4.Is there is a tutorial that thoroughly lists the steps and tools involved in this project?
5. What specific tools/skills will I need to be assured I remove and install the new seal properly?
6. What is a reasonable amount of time to plan for completion of this job?
