OK, I have a final update on this issue I was having. It was the distributor modulator (when I changed over to the Sierra electrical distributor package) the Chinese modulator was bad. So I ordered a S10 version from AC Delco(no brass screw holes but coated it good & I live in the desert) and...
I have the tab but the tape is a good idea since I have 4 different marks on my wheel, seems like every shop had their own idea on timing. 1 mark is mine from when the heads were off so I know it's 100% TDC and I can adjust from there.
I also have the extras for the distributor too, see pic...
Thanks, I ended up replacing the lifters anyways since I was 1/2 way there. Just waiting on the new gasket to deliver to put the intake back on. I did buy an old Sears timing light & rpm gauge so I can test it on the lake and make adjustments. I guess that makes sense since I was thinking I...
Before last year the boat ran great since 1998 (that's when the 1995 heads were changed) and the push rods and lifters I didn't change & they all seemed to be the same size. Last night I was pushing on all the rods and no movement but I just cracked it up to be that if one was going I might not...
This is the pic from putting on the heads after remanufacture. This is a 1990 everything except the heads are 1995 (old winterizing lesson) & before now boat shops have done all the work. I'm starting to think I might have a bad lifter and it's supposed to be done with the 1995 method of...
ok, I got it all done and she sounded good. With the earmuffs on but about 5 min in I started hearing a ticking with the rockers and it got louder. I just took off the valve covers and a couple nuts backed off a couple threads. Should I use the white thread sealer on the nuts to get them to...
OK, I finally had some time to work on the old boat again and I starter her up with earmuffs and the heard some slight ticking. I also noticed I have the plastic lifter brace so I tried the 1995 method and with ear muffs she sounded great so I took her out to the lake and did a couple 500 yard...
The rockers are non roller style. I have the engine buttoned up and just sitting right now, haven't even fired it up due to work and kids. I follow the lash technique in the manual but with 2nd guessing myself I'm going to do a compression test to see if they are too tight, before firing it up...
Thanks all! I'm mechanical but never torn apart a boat or car engine & the rockers was the part I just felt unsure. I ended up doing 0 lash and a full turn but the full turn didn't always happen as the nut stopped/bottomed out. So then I went back and did 20#'s on each one since I remembering...
This is the 1st head project I've done, or even tore down the engine this far. The boat has a 4.3 from 1990 but the heads are from 1995 (forgot to winterize in a non-cold state & had a shop replace the heads in 1997). Forward to 2023. I just got my heads back from the machine shop and I have...
