Long story short. I did the 120k service on my ‘91 with 158k. Recently got it, wasn’t sure anything was done. I put new seals on the crank and cams.
Yesterday, I buttoned everything back up and it was running the best it ever has. Just amazing. However, after driving around for like two hours I noticed my oil pressure dropping. No other real issues, so I thought it might be a bad pressure sender (I read that’s pretty common). Nope. I was pretty much home when I started hearing the ticking.
Now that I’m writing this out, I was noticing some dripping. I thought it was PS or AC. Was probably my crank seal.
Another thing to note is that I’m an idiot and mid-aligned the timing marks on the belt. I went off the dot on the crank instead of the dot on the sprocket. When I started it, it definitely had some interference, but a light tap. However, when I aligned everything correctly, it tapped a little, but then cleared itself back up. No issues over the several days that I started it before putting everything back together.
Ultimately it looks like I blew the crank seal thus causing oil starvation to the top of the motor. Definite tapping up top.
How screwed am I? Did I blow this engine? Fixable?
