    Thunderbolt V vs Delco EST Ignition

    Sounds like leave it as is then and return the Delco kit. I do have a small issue which is the timing jumps around by about 2 deg when in base timing mode. So hard to set exactly. It sounds like possibly distributor bushing? Timing chain is good. Is bushing a replaceable part and anyone have a...

    Thunderbolt V vs Delco EST Ignition

    I bought a Delco EST ignition conversion kit (Sierra) thinking my TB V module was bad. Then found out it was mechanical issue and TB V seems to be working. Question I have now is, is the Delco EST an upgrade? Or just keep the TB V installed? I can still return the one I bought. Or I could...

    No compression with rocker arms torqued

    170 deg, no higher. Shut down within a couple seconds of alarm. Ran today wide open fantastic with new water pump impeller and no temp issues. Mid 90s air temp too. But yeah, going to order a new thermostat just because I have no idea of how old current one is.

    No compression with rocker arms torqued

    Tested oil pressure sender vs mechanical guage, it was sending 20 psi below my gauge. So didn't lose pressure, it just went below 20 and looked like 0. Water pump impeller was torn too which prob contributed to overheat. No pieces came off luckily. So I think, fingers crossed, that I am good to go.

    No compression with rocker arms torqued

    Check plug gap, several a little too much gap, regapped. Number 8 plug tip (which I had dropped in the bilge yesterday) had basically no gap. Regapped. Hit 4200 rpm at about 28-30. Still too slower than it should be but I also have a broken anticavitation plate on outdrive lower unit, so maybe...

    No compression with rocker arms torqued

    That's interesting but it sits level at the factory waterline, bottom paint 3-5 in above water with 3 people and 100 gal of fuel/ water on board. So I really don't think weighed down.

    No compression with rocker arms torqued

    It's a 97 sea ray sundancer 270. To my knowledge nothing that really could be waterlogged.

    No compression with rocker arms torqued

    3800 rpm at 26mph WOT, so WAY better, but something is still off. Ive got coN pression close to 150 across the board. This is with 2 adults, 2 toddlers, 40 gals water and 60 gal fuel. 21 p new prop vs 23 p stock spec. Should be 4200-4600 and near 40 mph. i have the delco EST ignition kit from...

    No compression with rocker arms torqued

    Thanks, I'll listen for tapping. Having pulled the exhaust elbows and valve covers about 10 times in the last couple weeks, I can do it in about 10 minutes now. So no big deal if I have to dial in a bit.

    Random no crank on 5.0

    My ignition would do this sometimes, I put in new ignition switch and cleaned all wire connections with a rotary tool. Also make sure to clean the contacts on both sides of the ignition fuse. Don't forget to clean at the starter junction too. Mine hasn't done it since.

    What would be a sign that it is not enough?

    No compression with rocker arms torqued

    Overnight adjustable rocker stud conversion and nuts from Jeggs came in today. Just installed. Has never run so smooth. Purring and not a vibe. Went zero lash plus a quarter with irregular thread lock nuts. Too late to leave the slip so heading home and water test tomorrow. Dropped a spark...

    No compression with rocker arms torqued

    Update - back out here early. Focused on a bad cylinder (5) where I could easily pull lifters with a magnet. Interestingly I had good compression on this cylinder at before I started adjust valves the other day. Then it dropped off to 0 after adjustments. - 0 compression - loosened intake valve...

    No compression with rocker arms torqued

    Thinking more about the cam timing being off, it would be off the same for all cylinders right? So if one intake valve not closing, none would be? I have no issues with several cylinders, so I don't think that is causing this.

    No compression with rocker arms torqued

    It is but my concern that I took it off with slack on one side and put it back with slack on the other and that amounts to a tooth? Is that possible or would the rotation definitely show?

    No compression with rocker arms torqued

    How far before tdc on no 1 should no 1 intake valve close? I'm pretty sure on mine it closes a few degrees before I get to TDC but then the exhaust does not start to open for quite awhile. Starting to worry I'm off a tooth.

    No compression with rocker arms torqued

    And it's a month wait to even get a Mari e mechanic out here in DC area. I am wondering about lifters too. Here are pics of one of the bad cylinders valves. I have no clue what to look for.

    Can you link me to the adjustable stud kit? Will that use same rockers?

    No compression with rocker arms torqued

    No 1 intake closes just before timing mark on balancer when piston is at TDC. Camshaft had a guide pin as well so could only go on one way. Took old one off with gear marks pointed at each other and put it back on same.
