Learned it's sometimes better to pay someone else to do the work. I learned real fast I don't have the patience or skill for sheetmetal work involving anything past a stud welder. Getting impatient and half assing and going cheap on stuff just to get a car finished. I'm still dealing with that on my 87 turbo buick. It's cheaper to buy finished and then gut it to make it your own. Don't leave a rag in the engine. They don't care for that. Double check the marks on timing chains. Yup, chased my tail for over a year because of this. Don't tear down an engine before you find out exactly what's wrong with it. It's hard to fix what isn't broke. Using worm clamps on turbocharger piping isn't the best idea.
