Hello everyone. Went for a drive today and car ran great, stopped for fuel and when I started back up I heard a horrible rattle coming from cylinders 3 and 4 valve cover. After a tow home I found this. At least 1/4" gap from rocker to valve tip. I turned the engine over slowly and did get the rocker arm to slightly open valve. I thought how could a solid lifter collapse?
I also pulled the rockers and pushrod. The pushrod was not bent. I looked down the pushrod tube and saw 'C' clips on the lifters. Is there such a thing as solid lifters with 'C' clips? Thank's for the help. ![]() |

Probably not solid lifters, once the push rod is out you can pull out the lifter with your finger, after you remove the push rod tube.

Thanks, I'm working on getting the tube out now without crushing it.

Pushrod tubes aren't expensive. I spent hours trying to remove one without crushing it before finally taking the vice grips to it. Now I have one shiny one.
Good luck! Hope it's a simple fix. |

Better than a dropped valve seat.

It was obvious that it’s hydraulic once I pulled it out. I was told this engine was built with a Webcam 86 so assumed it had solid lifters. Now what to do? Solid lifter swap.

Solid lifter swap. lifter brand and quality is often matched to the cam I believe cams for hydraulic lifters are mild there are a number of experts on here (not me) that can advise but my limited knowledge is that you may have to go back with another matching hydraulic lifter to work with that cam profile. or split the case and replace the cam with matching solid lifters brant |

I'd double check with Web on that lifter. Their performance lifters look like hydraulic lifters, but somehow work as standard lifters. I just finished installing a set on my engine paired with their 86a cam. Threw me for a loop when I took the lifters out of the box.
I'd also compare the stem heights on the valves and do a leakdown check. Higher likelyhood that you have a dropped seat rather than a lifter issue. BTDT. |

Have you taken the lifter apart yet? Wondering if the spring is broken.

(IMG:style_emoticons/default/agree.gif) if it was Hydro youd normally have other somewhat obvious signs like solid steel push rods (not the OE thick wall alum)

(IMG:style_emoticons/default/agree.gif) I did see Webcam lifters that looked like hydraulic lifters. These look exactly the same.

The ones you posted the Pelican link for are the exact ones I installed. Web's site lists them as mechanical, and they are still set with the normal lash the stock lifters use. Called them to verify after I unboxed them.

pretty simple at this point to verify, pull another lifter & compare the two. My bet is they'll be the same. Looks like a seat.

Sorry to say, but based on your description (especially the noise), you're probably looking at a valve seat that let go.
Here's a very useful tool that you can feed either through the spark plug hole or manifold. It's useful for many other jobs too and is less than $20 delivered. Please note that this one works on an android phone. If you have an iPhone get a different one. https://www.amazon.com/gp/aw/d/B071HYRPND?p...ob_b_asin_title Best wishes with the fix. |

Thanks guys. I have that same camera for Iphone. I'll measure stem heights and scope it tomorrow and get a leak down tester.

Do you have a dead sound when cranking the starter? The starter will make some noise when turning over a cylinder that has compression, and no noise (or rather, less noise) when turning over a dead hole.
Check the height of the valve tips when the valves are closed. If the one is lower than the others, something is holding it open. That something is usually the valve seat. --DD |

From the picture, doesn't look like a dropped seat, a differential test would help confirm that. That rocker looks pretty far "back" compared to the others while the top of the stem looks in line.
If it's just a lifter, agree with others, ensure to confirm your cam, get a matched lifter. You may get lucky that's all it is. |
